Voltage sensor is not working on Microstorm Prototype V2

Reason

Due to a issue in the board design one of the resistors is wired in series with the enable pin of the switching regulator IC.

Fix (kind of)

There is a trace running from IO pin 4 of the ESP32. If you remove this connection the switching IC is working, but the voltage sensor cannot be used.

Recommendations

  • From the expansion header of the board the VCC and IO pins are broken out. You can create you own voltage sensing module by creating your own expansion board. Wire it as shown here (tested):

  • Use a Microstorm Prototype V3 PRO

Note

This issue has been fixed with every board distributed. Working fix is also located on Prototype V3 PRO.
