Cause/Symptoms |
Possible Solutions
|
Pinecil doesn't power on at all
|
Faulty PSU
|
Check your PSU with another tool or a multimeter
|
Faulty cable
|
- Check cable with another device
- Use a different cable
|
Internal problem with power
|
Use different kind of PSU (if you're using a barrel jack one, try a Type-C one, and vice-versa)
|
Pinecil shuts down when connected to a Type-C PSU and trying to request a higher voltage (Title needs a bit more clarification)
|
Out-of-date firmware
|
Update firmware - factory firmware has quite a few USB-PD problems, which the newer firmwares fix. See the update documentation on GitHub
|
Pinecil randomly resets when touching solder or doing other things
|
Using PinePower or some other non-grounded PSU
|
This is likely to be a "lack of grounding" problem. When using Pinepower, you can unplug the figure-8 AC cable plug (on the back), rotate it 180 degrees and plug it back in - this tends to remedy the problem (insights)
|
Doesn't power on after applying 24V to the barrel jack
|
Damaged USB chip
|
The FUSB302 might have gotten damaged and shorted an internal power rail
- Use a hot air gun to remove the FUSB from the board. You can leave the iron without the FUSB302 IC, or you can find and buy a replacement.
- Without the FUSB IC present, you will lose USB-PD compatibility - the Type-C jack will not power your Pinecil with a C-to-C cable, or from a PD-capable PSU with attached type-C cable (laptop PSUs)
- You will still have USB QC support without the FUSB IC, and all the other features will keep working!

Pinecil tip heats up too much, starts to glow and [REDACTED]
|
Heats up when plugged in, without pressing any buttons
|
Likely a FET failure - the FET can be replaced. by using a hot air station or a soldering iron.
|
Heats up after pressing the button
|
Likely to be bad soldering of the thermocouple amplifier IC. Resoldering the thermocouple amplifier should fix this problem.
|
Either way, you will want to replace the tip after it's heated up to the point of glowing, as the surface coating is likely to have gotten compromised.
