Main Pin Definitions


Arduino Demo Code

  • Based on Arduino TFT_eSPI library
  • Add extra pin definitions, demo code please see here (Arduino-ESP32/Sketchbook/Display/).
  • Working demo please search social channels


  • Please attach battery, and plug USB to "activate" battery first, once you removed the battery you may need to activate it again
  • Battery port, I2C port pitch 1.25 mm, speaker port pitch 2.0mm
