Re: ESP32-H2 powered by LiFePo4 battery

It's working now.
I found out, that INPUT for battery should be on 5V (+) and GND (-) pins. Also another problem was, that after flashing HA_on_off_light example I had to push BOOT and then RESET button, unplug BAT and plugin it back.
Then HomeAssistant finds ESP32H2 module and LED started to work.

Re: ESP32-H2 powered by LiFePo4 battery

Because full charged LiFePo4 battery has around 3.5V and when it's nearly empty it has around 3.2V, so the best solution for power supply ESP32-H2, which is suitable from 3.1V to 3.5V I think.

ESP32-H2 powered by LiFePo4 battery

Hello guys, I'm using ESP32-H2 and I wanted to power this up with LifePo4 battery (32700). Unfortunately I'm not able to power ESP32H2 up. I connected "+" to 3V3 and "-" to GND pin and nothing happens. Battery has been charged to full capacity and voltmeter shows me around 3.44V. Also I've tried one...
