  • You will need a USB-TTL adapter bridge board or cable, to interface or program ESP32 via the serial interface

To communicate with ESP32 normally, connect (working mode):

  • TXD->RXD, RXD->TXD, +5V=+5V, GND=GND
  • remove IO0-GND jumper, IO0 LED should be off

To program ESP32 (flashing mode):

  • Connect the same serial interface
  • Put IO0-GND jumper ON, IO0 LED should be ON
  • press reset button to enter into flash mode
  • Upload arduino demo code
