7.5inch e-Paper (B), 7.5inch e-Paper (C), 7.5inch HD e-Paper, 7.5inch HD e-Paper (B)

Note: The ACeP e-Paper doesn't support this connecting method.

  • e-Paper Module/HAT + ESP32 Board
If you have the ESP32 Board as well as the e-Paper module/HAT which has PCB already, you can wire the displays by 8-pin cable pin
Connect to ESP32 Driver Board
e-Paper ESP32
Vcc 3.3V

Run the Demo Codes

  • Open the Arduino IDE
  • Choose File->Examples-> waveshae-e-Paper -> And the project according to the type of display
Epd esp32 example 2.png
  • Build and program the ESP32 board
  • Open the serial monitor, you can check the degbug information when runing the demo codes
