FireBeetle ESP32 - Battery level and wake up from charging
studio 2021-03-04 15:24:02 2277 Views4 Replies Hi,
Just ordered multiple FireBeetle ESP32 units. Hearing great things about them! I do have some questions:
What is the correct way to measure the LiPo battery level on the FireBeetle ESP32?
Is it possible to wake from deep sleep, when battery is being charged / USB voltage is applied?
Is is possible to know when charging? There is an led indicator, but I want to know the charging status in my Arduino code.
Thanks!

2021-07-22 22:23:49 I went ahead and tested it. Looks like pins A2 (34) and A3 (35) would be usable.
A4 always reads a 0, and A1 is the same as A0 mkollek

mkollek 2021-07-22 08:26:12 Does this meet that all you need to do is bridge those two and do an analog read from A0?
If I do that I can still use one of the other A1-3? Pins to read analog from a soil sensor? mkollek
