It used to work fine on both USB and battery. I have no idea what happened, it just suddenly stopped working on the battery connector. Anyone have similar experience? I’m hoping its just a diode, resistor or voltage regulator.
HT v3 runs on USB but not battery
Sort of a stupid question but can you check that the battery leads are intact and that the power gets to the battery connector on the board. Also try to run a test code that reads and prints out the battery voltage ADC to see if it works. Also check if power goes to the connector for charging when on USB.
