# 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
  • USB Type-C interface
