We currently have a designed PCB / schematic but need some changes and features added. All design has been done in kicad and project files will be provided for you to work with.
Project is based around the ESP32-WROOM-32 module and is quite basic.
Changes required are:
- Change from USB Micro to USB-C connector (Power Only)
- Add power on button With following functions
--- Device should be off by default
--- One Press should turn device on
--- Button state should be readable by ESP32 (can detect the button press state)
--- Power off can be controlled by ESP32
- Add LIPO Charging
--- Device should run on USB power if battery is low charge
- Add battery status monitoring (Replace current solution using voltage divider)
--- Need to be able to get battery Charge percentage + charging state (Charging or not charging)
