BTClock v2

Improved code for BTClock with many features. Don't forget to copy config.h.example to config.h. Not necessary to adapt it, since everything should be configurable through the WebUI.

Software

Hardware

  • MCU: ESP32 or ESP32-S3 (Wemos S3 mini recommended)
    The ESP32 S2 is not supported, it does not have enough RAM
  • Seven eInk displays
  • MCP23017 I2C Port Expander
  • 4x WS2812B leds (optional)
