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

  • Micro USB interface
  • Overcurrent Protection for USB
