I wonder if there is a way to use an external power switch to power on/off the D32? I'd like to be able to use a battery connected to the onboard JST connector. To power the board, but also to be charged via USB. I've done a bunch of research, but don't want to go ahead...
The ESP32 is intended to be suitable for low power applications - in other words, running on batteries. The optimal voltage for the ESP32 is 3.3V. The nominal voltage of a Li-ion battery is 3.7V but it can be anywhere between 3V and 4.2V. Many of the development kits come with the...
