ESP32 Universal Raw e-Paper Driver Board WiFi Bluetooth

Practical Universal e-Paper Driver Board with an ESP32 microcontroller for direct connection of raw e-Ink displays. With this ESP32 Driver Board, you can directly connect our inexpensive raw e-Paper displays (e-Paper raw panels without board) to the ESP32. Waveshare already provides a sample code that you can load onto the ESP32, allowing you to upload and convert images directly from a website. The images can thus be easily displayed on the e-Paper display via WiFi or Bluetooth.
