Remarks:

  • LED is connected to GPIO-00
  • BUTTON is connected to GPIO-31
  • LCD (SPI1,GPIO-02,PWM-00) & TOUCH (SPI2) pins are available for use in non-LCD models.
  • CLKIN pins can only be used for input.
  • UART0 is reserved for the USB-Serial Console.
  • Incorrect I/O pin usage can damage the board.
