I was annoyed using standard esp32 devboards for projects. I always needed to include battery, charger, protection and usually also 5v boost for other devices. So I desided to make a complete board to accelerate prototyping.

This board is made for esp32-s3 or s2 that have their own usb interface. If you are using standard esp32 then you need to use external usb adapter on the uart pins.

Board in the picture is the first revision, in that I did multiple mistakes, biggest one was forgetting pull-up for the GPIO 0. (You can see the fix on the picture) Latest should have all the following fixes:

- Change the USB dataline series resistors from 22ohm -> 0ohm
- Fixed the boost IC:s output prog voltage divider
- Added pull-up for the BOOT pin

I will be doing further testing for this board:
- Current consumption/battery life in different scenarios
- Vcc, 3v3 and 5v boost transient and ripple
- Charge profiles
- Power path switching
- VCC voltage measurement calibration for
