WIP: USB Current Meter w/ BLE + Touchscreen

This project is still in the making...

This is going to be a battery powered Current Meter for USB devices with Bluetooth LE support and a touchscreen for operating the meter.

  • ESP32 WROVER-B with 520kB SRAM + 4MB SPI-RAM, 16MB Flash, 2x 240MHz
  • Firmware is written in MicroPython
  • 2.8" 320x240 pixel Touchscreen w/ SD-Card slot
  • 16-bit ADC connected via I2C
  • Li-Ion battery and USC-C charging port (the charging circuit is on the ESP32 board)

The current prototype is not very pretty, but the final product is hopefully going to look better :)
