zikken:
I have several ESP32S3 board. I’d like to use them in a setting where mains power is not guaranteed. The idea was I hook up batteries to the device, and mains power.
My expecation was for the device to switch automatically and charge when needed. It does not.
it resets when there is a battery connected and it’s on mains power using the USB connector, and one then unplugs the USB.
Also, if the battery is disconnected and then connected again to a running device, it does not start charging.
Anyone got experience with this? As it is right now, it’s unusable.
Check which PMIC your board uses, if any.
