What's it

A CP2104 3.3V USBToUART converter support 400mA+ current. Program ESP8266/ESP32 module just like NodeMCU. It has smaller size than rev2 and we make it breadboard friendly. You can also use the flasher to programming ESP32 without pushing flash button.

What's Difference

  • USB Type-C interface
  • Add jumper for support 1.8V and 3.3V GPIO voltage
  • Add P1 pinout to support more GPIO
  • ESD and Overcurrent Protection for USB
  • Add support for USB to RS485/RS232 convert

RS485 And RS232
