Instructions to Install a Hall Effect Sensor (HES)

The Hall Effect Sensor (HES) is an optional end user installed sensor that activates to put pinecil to sleep when it enters a holder or stand. This requires a magnet attached to the stand. The closet the HES in the pinecil is to the magnet, the more likely the HES will activate. This adds a feature to Pinecil that is often seen in high end pro irons.
Order an SI7210-B-00 HES here, also available on Digikey and Mouser.
Ordering 2-3 might be a good idea in case the first one is damaged during install (if all goes well, could mail the extra to a friend or Pine64 member).
See this article explaning how the Hall Effect Sensor (HES) works with Pinecil firmware, Ralim's IronOS.
Once it is soldered completely and assembled, check the Sleep menu, a new Hall Sensitivity option appears, see the Github article linked above for details.

Updating to the newest firmware before installing is recommended, see the Firmware article.
Try not to overheat the sensor while soldering as that could damage it and even cause a leg to fall off. This is a very small SOT23 chip. Tacking one pin on the 2-pin side helps to hold it in place before soldering the rest of the sensor.
Apply some soldering flux to the area to be soldered.
Clean the area with isopropyl alcohol (IPA) and allow to dry before assembly.

Borrow a second soldering iron (this is when 2x pinecils is a good idea).
Get some neodymium magnets, even just two 8x2.7mm at 8:00PM and 12:00PM on the stand could be enough. Experimentation is needed. Start with just one small magnet and increase the number places on the stand until 360° sleep is activated when the pinecil hits the stand.
Lamp with a Magnyfying glass or Jeweler's magnyfying glasses or a microscope is recommended.
If the stand/holder is not metal, one could hot glue or tape magnets to it.
