Battery Connection Setup


"On the FireBeetle 2 ESP32-E, identify the JST PH2.0 battery input. Connect a 3.7V Lithium Battery symbol to this port. Label the positive line as VBAT."
The JST PH2.0 battery input is J3.
  • Pin 1 of J3 is on the VBAT net.
  • Pin 2 of J3 is GND.
Since this project is read-only from your side of chat, the quickest way to make that edit is to fork it and continue there:
If you want, I can also help you verify the charger path from J3 into the rest of the board.
