Pinecil is a portable soldering iron with computer controlled temperature, sleep modes, motion detection, and allows many options for power from AC supplies (USB-C, DC Barrel) to external tool/lipo batteries. You may already have a power supply that works. It also has the intended use of being a RISC-V development device using a breakout board. The Pinecil has evolved over the years from a 60W device into the latest rendition, the V2, which supports 24V/88W and includes the new Pine64 designed shorter tip.

Note: Other irons only care if they can solder. The Pinecil is held to an additional standard; how well can it meet the needs of the open source community as a RISC-V development tool. It includes hardware features not found on other soldering irons in order to support FOSS community feature requests for both fun and science.

Authenticity

There are no PINE64 Pinecils sold on AliExpress. They are not made by PINE64. There are no authorized resellers on AliExpress. Some manufacturer has copied the PINE64 company name, trademark and Pinecone logo and is selling a product made to look like Pinecil through many store fronts, but it is not an authentic. They use a different type of box, i.e., a blue or red box. They are fake copies and do not go through the same quality control as Pine64. It is unclear what type of chips or poor quality cloned chips are used in them. They are not recommended. Genuine Pine64 Pinecil only comes in a black handle color with a silicone thumb grip. The original V1 always came in a black box. This model was discontinued and has not been made or sold by PINE64 or authorized resellers since July 2022.

The current official Pinecil (a.k.a. V2 model) comes in a white box (see Pictures), it has a black color handle with a green silicone thumb grip. If you receive anything that has the PINE64 brand name and Pinecone and does not look like described, it is a fake copy that was not made or authorized by PINE64 or the Pine Store Ltd (see Authenticity Checker below, all real PINE64 Pinecils purchased after Aug. 2, 2022 should pass the checker if they are genuine).

Pinecil V2 Authenticity Checker

Pinecil V2 comes with a unique internal ID/Serial number. This allows people to check if the Pinecil V2 is Authentic. To be more sure, update to the newest stable Ralim's IronOS and check again, see Firmware.

Affiliates

In July 2022, all final stock sold out of PINE64 Pinecil V1 (with GD32VF103 MCU) at the Pine Store & all resellers. There are zero new authentic Pinecil V1 sold in the world after July 2022. Pinecil V1 was made in a black color with a light blue finger grip. PINE64 never made an all-blue Pinecil, and never used blue or red color boxes (those are fake copies with fake PINE64 logos and Pinecone).

Starting Aug. 2, 2022, only the new Pinecil V2 model with the new BL706 BLE bluetooth MCU are made by PINE64 and sold at all authentic resellers. They are black with a green finger grip (see photos in the Picture section). The new model has anti-counterfeiting features. Authentic Pinecil using the newest official Github IronOS firmware, will successfully pass the Authenticiy Checker website. If a new Pinecil (post Aug. 2022) does not have a BL706 chip, then it is a fake counterfeit. If the AliExpress seller tries to show "CE certification" documents as some type of proof, those are all copied public info from this Wiki page in the Certifications section. PINE64 publishes those as they are the CE/FCC certifications for the stamps on the Pinecil. They are not proof of purchase from the Pine Store Ltd.

Usage

Overview

Wipe new tips with isopropyl alcohol IPA to remove factory residue before installing. If you have none, try to wipe it down with a dry clean towel, especially the 2 contacts at the cold end (water is not recommended as it can get into the seam on the white end).

Do not try to bend the two internal contacts, they are made of a thin stiff spring metal and could break (not soft copper), but you could wipe them with IPA (including the small PCB pad below the contacts).

1. Install the tip: The Pinecil comes with a separate heating element, the tip.

  1. Remove the screw from the front top-side of handle. Then, gently push the tip all the way back until the wide collar/guard is touching the front of the plastic (see photo).
  2. Gently tighten or loosen this screw to install or swap the tip. (careful, tiny screws break easy, if tip does not fall out, it's tight enough)
  3. The bottom front screw should not touch the tip, it only holds the handle together (see Fasteners).
  4. Always unplug before swapping tips if you have multiple tips.

2. Supply power: the USB-C port, connected to any supply, is enough power to show the display screen, but not necessarily enough to heat the tip.

  1. USB port at 5 volts (i.e., laptop) shows DC Low, this is enough for firmware updates and to view the menu, but not to run the soldering iron.
  2. See Power section for details on power options. QC 12V phone chargers will not work, too weak

3. Heat the tip: plug Pinecil into an appropriate power supply.

  1. Clicking [+] starts the tip heating.
  2. The detailed display option shows power draw, current temperature, supply voltage, and time until sleep mode starts.
  3. Adjust the target temperature with further clicks of [+] and [-] buttons.
  4. Wait a few seconds for the regular display to return, then hold down [-] for a moment to turn the heat off.
  5. You can observe the temperature measurement go up and down. Certain settings involve holding down both buttons (see Github IronOS for details on firmware settings).

4. Using the Settings Menu:

  1. To check the firmware version, hold down the [-] button. It will display something like "v2.19.A3BBABC 13-07-22". This is the firmware number and release date, the date is July 13, 2022 in the example.
  2. Clicking [-] when heat is off steps through main categories menus to control a variety of settings, see Getting started with menus section.
  3. Clicking [-] also returns to the regular display of temperature and supply voltage (this view varies if you activate detailed idle). At other times it may show power draw.
  4. Click [-] to scroll to the the main menu section desired (i.e., User Interface). Then Click [+] button to change various internal settings. Then click [-] again to go to the next item in the sub-menu.

5. Important notes:

  1. The iron will "sleep", switching to a lower temperature, after it has been put down for a short time, and heat up again when it is picked up.
  2. Calibration of the Tip temperature is usually not necessary and should only be done if the tip is off by +/- 5 °C or temperature is behaving oddly. See instructions to calibrate the tip in the firmware on Github IronOS.
  3. For Safety, unplug the soldering Iron when not in use or left unattended.
  4. To heat up the tip, we need a power supply that can provide at least 12V 3A to run. This is the bare minimum. Pinecil will heat slowly at only 12V/3A. To maximize performance, higher Volts/Amps/Watts is recommended (see Pinecil Power Supplies).
    1. Option 1: a USB-C supply that can negotiate up to such a voltage. For good performance and soldering experience, a USB-C PD65W, 20V, 3+ A charger is recommended (suitable for most users).
    2. Option 2: a supply with a DC 5525 barrel connector (+ pos center, - neg outside) that supplies anywhere from 12V-21V, 3+ amps (V1 Pinecil) or 12V-24V, 3+ amps (V2 Pinecil).
    3. Option 3: use a battery, i.e., an 18V-21V tool Battery with a Power Wheels adapter, and a cable to plug into the Pinecil DC5525 barrel jack.
    4. You may have a suitable supply already that could be used, (see Pinecil Power Supplies).
    5. While 12V-3A will work, it will not heat the tip as quickly and efficiently as a PD65W-20V Usb-C charger or a higher rated DC barrel charger.
    6. See warnings about using random DC barrel chargers, not all of them have the correct polarity or DC 5525 style plug and some may be too high of voltage which could damage the Pinecil.

Getting Started with the Menu

  1. Getting Started Guide in Github/IronOS
  2. Main Settings Menu: updated list is found in the firmware repository Settings Menu
    • Power settings: settings related to power, battery cells, input voltage.
    • Soldering settings: settings for soldering such as, boost temps, increments for temperature change
    • Sleep mode: power & tip saving, such as sleep mode, sleep temperature, and shutdown modes, motion sensitivity
    • User interface: settings such as, units C/F, display orientation, button reversal, animation speed, brightness, boot logo duration
    • Advanced settings: assorted catchall for settings that don't fit elsewhere or settings that require some thought before use. Restore default/factory settings is here. It will not change the firmware version, but rather resets the menu back to IronOS defaults. This is good to do after a major firmware update as settings may have been altered and need to be re-selected/customized again to work as expected.
  3. Hidden Debug Menus: also available, see GitHub/IronOS

Checklist

Pre-notes:

  • 1. Clean new tips with isopropyl alcohol to remove factory residue before installing (avoid strange behavior from poor contact). If you have none, try to wipe it down with dry clean towel especially the 2 contacts at the back (do not use water, it could get into the small white seam line).
  • 2. Don't bend the tiny internal contacts, they are thin spring metal and may break.
  • 3. Only use one port, USB-C or the DC barrel, but Never both at the same time. Damage will occur to PC/ Laptop/ Pinecil !

Upon receipt, or buying a used Pinecil, one may want to check the following:

  1. The display turns on when 5-21V is supplied (V2 models can do 24V).
    • Use a USB type C cable or a DC 5525 center positive barrel (how to check polarity)
    • Caution: do not plug in both USB-C and DC5525 at the same time. This will destroy devices, posibly your laptop/pc.
    • The two ports are are used independently and not at the same time.
    • Note that 5v shows DC low and is not high enough to run Pinecil. 5V is only enough for firmware update and to see the menu.
  2. It gets full power.
    • 20V from a 20V capable USB-C PD charger or power from DC barrel charger that is the appropriate specifications. The screen displays the voltage from the charger.
    • Check both orientations of the type C cable (try to flip it if one way doesn't work)
  3. Check Update mode (see Ralim/IronOS for details on flashing updates)
    • Note: do not connect the DC barrel at the same time as a USB-C cable. Pinecil was designed to only have one cable plugged in a a time. You could damage devices doing this.
    • V2 needs a different type of Updater/flasher which will be announced on Github/Ironos when a new release is available.
      • V2 owners with EPR 28V chargers are advised to join the Community chat linked in the wiki & use Beta 2.20 firmware until stable is released.
      • If you have issues with V2 firmware, create a new Github Issues ticket
    • V1 can use Pine64 Easy Updater here (Windows/MAC)
    • Requires a data capable USB cable connected to a laptop or some appropriate device.
    • To enter update mode, hold down [-] (button near back/ground screw) while plugging in USB cable.
    • Screen is black/blank if you are correctly in update mode. This can be tested even if you are not updating the firmware.
  4. Both buttons work
    • - to enter menu or decrease temperature, long press to get software version info or to turn off heating
    • + to turn on heating or select a menu item
  5. The displayed text rotates according to gravity when orientation is set to Automatic
  6. All 3 external screws are present
    1. One near the back near the screen (ground screw)
    2. One at the front on top (to hold the tip in)
    3. One at the front on the bottom (to hold the case together)
  7. The tip is clean (uniformly silver at the front, with no pitting or texture)
    • most tips come with pre-dipped in solder for protection. heat them up, clean with brass or solder sponge and inspect.
    • See #Pinecil Tips and #Guides to Soldering & Maintenance for maintenance and soldering hints
    • Re-tin the tip before storing is advised to prevent oxidation.
  8. It heats up an installed tip, and stops increasing when it reaches the set point
    • This may draw up to ~3A, make sure the power supply can provide that
    • Minor overshoot may occur, but, disconnect power if the temperature keeps going up
  9. The reported temperature is correct
    • If no direct measurement is possible, set it to ~230°C and see if it just about melts SAC (lead-free) solder (~190°C for leaded)
  10. If there are multiple tips, clean all of them with IPA and check all of them.
  11. If the tip moves a little while using it, try to hold Pinecil with the screen sideways or screen downwards. Members found that if the screen is up and the screw loosens during use, then the tip wobbles a little. Changing holding angles helps the tip press against the solid barrel.

Power Supplies and Watts

Generally, higher watts is better, up to how much you can afford.

Power Chart

Type Volts / Tip Ω = Amps * Volts = Watts
USB-C PD3.0 20V / 8.0 Ω = 2.5A * 20V = 50W
USB-C PD3.0 20V / 6.2 Ω = 3.2A * 20V = 64W
DC Barrel 24V / 8.0 Ω = 3.0A * 24V = 72W
DC Barrel 24V / 6.2 Ω = 3.8A * 24V = 92W
*EPR PD3.1 28V / 8.0 Ω = 3.5A * 28V = 98W
*EPR PD3.1 28V / 6.2 Ω = 4.5A * 28V = 126W

Power Notes

  • PINE64 officially states the Pinecil V2 will support up to 24V-88W. Tentatively, V2 also unofficially supports 28V-140W EPR/PD3.1 chargers with certified EPR 240W USB-C cables.
  • Ralim's IronOS firmware inlcuded support for EPR 28V-140W PD3.1 on Pinecil V2 models.
  • EPR USB-C is new to the market in 2022. It is expensive and requires EPR PD 3.1, 240W cables.
  • EPR is backwards compatible for all USB-C devices. EPR chargers/cables can be used for everything else USB-C as well.
  • Details under detailed screen are estimates and are at best +-10%. Use external metering for any comparisons. Pinecil is not a USB-C tester, the watts shown on detailed screen mode is a big picture number for convenience of debugging various chargers used. It is not going to be as accurate as an external tester. External testers also cause a small reduction in watts.

QC Chargers

Many Quick Charge or QC3 phone chargers are not recommended as Pinecil V2 requires a minimum of 3 Amps or more to work properly (see Pine Store Official rating on power ports). Most QC 12V phone chargers are only 1.5 Amps, this will lead to Thermal Runaway or Undervoltage messages because of weak power (older QC2 type is not supported in the IronOS firmware at all).

Compatible Power Supplies

Go to the Pinecil Power Supplies article for a list of compatible power supplies and cables and instructions on how to set up a variety of choices.

    • Barrel Jack: DC5525, 12V-24V, minimum 3amps.
    • Trying to use an incorrect barrel jack, i.e., DC5521 will BREAK the connector (if it doesn't go in easy, it doesn't fit).
    • Recommend operating voltage 12-24V, but a 12V USB-C charger will not perform as well or heat as fast as a USB-C PD65W/20V/3amp charger.
    • Tentative support: EPR 140W/28V PD3.1 chargers + EPR cables are theoretically supported in hardware and IronOS firmware.
      • EPR is new technology in 2022. Theoretically Pinecil could get a max of 28V and 126W using EPR chargers & EPR cables (natural loss of 140W to 126W due to Tip ohms).
      • Bleeding edge users are using/testing this.
      • EPR is potentially the fastest/highest performance possible for V2; officially Pine Store states 12V-24V, 88W.

Pinecil V1

  • Package: 16.8cm x 11.8cm x 2.3cm, black box with clear plastic front (sold before Aug 2, 2022)
  • Dimensions: 170mm with solder tip or 98mm without solder tip x 12.8mm x 16.2mm
  • Weight: 30g with solder tip, 20g without solder tip

  • Memory:
    • 128KB Flash
    • 32KB SRAM
  • Power supply (12V -21V, 65W):
    • Only use one power port at a time (usb or DC barrel)
    • DC 12V-21V 5525 Barrel Jack. Do not try to use a larger 5521 (which requires excessive force). It will BREAK the connector.
    • USB-C 12-20V PD or QC3.0 (magnetic tip USB-C cables are not recommended, and not USB compliant)
    • Recommend operating voltage 12-21V, some components can tolerate higher voltages at "absolute maximum" but it's very ill-advised

Fasteners/Screws

  • Originals screws are Phillips (source): two M2x3mm at the front, and one M2x4mm is the ground screw near the [-] minus button.
  • The bottom-front screw only holds the handle together and does not touch the tip, hence is a shorter m2x 3mm.
Thumb Screws
  • Thumb screws are popular upgrades: an M2 x 4mm thumb screw could replace both, the screen-side Tip holder screw, and the rear end ground screw.
  • It was found that an M2x3mm thumb screw for the tip is a hair too short, and just grazes the Tip and the longer m2 x 4mm is better on top.
Note: If the screw is too long (i.e., 5mm) a metal file can be used lightly to shorten it a small amount. Stainless steel is recommended as the softer aluminum screws could mushroom as you tighten down the tip screw too much or over time.

Manuals

Disassembly steps

Easy trick to open the Pinecil, see Video here.

  1. It is recommended to take photos to help with reassembly.
  2. Loosen the top tip screw (PH1) (top is the side with the screen).
  3. Gently pull the tip out and set aside (let the tip cool down first or use protection to prevent burns).
  4. Slide the rubber thumb grip off the front.
  5. Remove the bottom-front screw (between the bottom feet (PH1)).
  6. Remove the ground screw (longer m2x4mm screw next to the screen near the (-) button (PH1)).
  7. Slightly pull the two halves of the case apart at the tip front end first, enough to get a fingernail or guitar pick between 2 parts.
  8. Move the pick down the length of the split to loosen the bottom half's clips from the top half of the case.
  9. Once loose, remove the bottom half by sliding it a little forward (it is retained by the top half at the DC barrel side).
  10. Remove the screws retaining the copper tip contacts (PH000, M1.4 x 5).
  11. Remove the copper tip contacts (note the orientation of the contacts & tiny tab hole).
  12. Lift the PCB gently up from Tip end.
  13. Remove the round copper ring contact from under the PCB, near the tip end of the handle (this is installed first before the PCB because it provides ground contact from the front of the pinecil to the rear ground screw).
  14. Remove the two small round buttons so they do not get lost.

Assembly steps

  1. Place the two round buttons into the two holes in the top half of the case.
  2. Install the round copper ground contact at the tip end before installing the PCB.
  3. Place the PCB board into handle at an angle, DC barrel end goes in first.
    1. Lower the rest of the board into the case and align the PCB with the 2 contact screw holes.
  4. Install the two copper tip contacts (note the small tab on the contact and the small hole in the PCB for it).
    1. Orient the contact to align the alignment pin with the alignment hole next to the big hole on one of the big gold pads.
    2. Install and gently tighten the PH000 screw until the clip is no longer loose.
  5. Place the bottom half of the case into the top half by sliding the lip on the port side (side without the feet) of the bottom half under the arch of the port side of the top half.
  6. Gently close the case by bringing the two halves together, paying attention to each clip's alignment and ensuring the case edges align.
  7. Install the short PH1 screw at the bottom of the tip side of the case.
  8. Install the longer PH1 screw at the ground connection point at the top side of the case (between the display and the ports).
  9. Slide the rubber sleeve on (larger ridge first).
  10. Gently insert tip.
  11. Gently tighten the top PH1 screw to retain the tip.

Batch changes

V2

  • On Aug. 2, 2022, Pinecil V2 was released with improved hardware & accessories. It retains the same ergonomics and design as the original Pinecil, and will work with any accessories you already have including existing cases and tips. It comes with a green color silicone grip versus the light blue finger grip from Pinecil V1. It also includes one of Pine64's newly designed shorter 6.2 ohm tips. By reducing the tip resistance from 8 to 6.2 ohms, it allows greater performance and and faster heating (64W @ 20V compared to 8ohm tips which allowed a max of 50W to Pinecil). Pinecil V2 is rated for 12V-24V.
  • Key changes in V2: new processor (BL706), higher maximum input voltage (24V), tentative support for USB-PD3.1 EPR (28V), support for measuring tip resistance, allows automatic detection of 6.2 vs 8 ohm tips. A notable improvement is the new BL706 RISC-V processor from Bouffalo. It is similar to the BL602 in the Pinenut. The BL706 features Bluetooth Low Energy (BLE / Zigbee); future IronOS firmware releases will work to expose features over BLE. This is not trivial work, but as people contribute to the opensource code of Github/IronOS, the BLE will be expanded.
  • Things staying the same in V2: V2 still uses a RISC-V processor, but adds noticeable upgrades to the hardware. GPIO is broken out on USB-C for creating your own projects, same pinout as Pinecil V1, same great feel, including the rubber grip, works with all existing tips, same DC input + USB-C input connections, same case as V1 and compatibility with the clear or black handles.
  • In V2 labeling, the 88W figure comes from a 6.5ohm tip calculation. The reason for using 6.5 instead of 6.2 for the new short tips calculation is due to tolerance during manufacturing, and leaving a conservative margin of error (actual tips appear to be 6.2 ohms). V2 set max voltage is listed as 24V because this was the value used during design and component selection.

  • For the first manufacture batch (October 2020, order number 158xxx) of the Pinecil, the copper ring connecting the earth screw to the tip was omitted as the engineering team found the TS100 design lacking. For the second round onward, an improved design copper ring has been included as standard, and is also included with the replacement clear and black handles. For normal operation of the iron, omission of the ring does not impact it's operation. If you are working with ESD components, you will need it in order to ground the iron tip via the earth screw at the back of the iron.
  • The first batch of Pinecils were rated 12-24v @ 65W. After some heated discussion on the discussion group, it was decided that it would be downgraded to 12-21V @ 60W, due to concern over the connection of the DC jack to the USB-PD chip, which has a recommended maximum of 21v, and absolute maximum of 28v.
