The NodeMCU R2 is a Wi-Fi development board based on the ESP8266 (ESP-12E module), featuring a CP2102 USB-to-UART bridge for reliable programming and debugging. It integrates GPIO, PWM, I2C, 1-Wire, and ADC on a single breadboard-friendly board, and can be programmed with the Arduino IDE or NodeMCU Lua firmware.

The R2 version improves on the original with a CP2102 USB chip (replacing CH341) for better driver compatibility, higher current support, and a slimmer form factor that fits directly on a standard breadboard.

Key Features

  • ESP-12E Wi-Fi Module – ESP8266 with 6 extra GPIOs compared to the ESP-12
  • CP2102 USB-to-UART – Reliable USB interface, no CH341 driver needed
  • Arduino IDE Compatible – Program directly using the Arduino ecosystem
  • NodeMCU Lua Firmware – Pre-flashed, ready to use out of the box
  • Breadboard Friendly – Slim design fits standard breadboards
  • Micro USB Power – 5 V power, programming, and debugging via micro USB
  • GPIO Access – 2× 15-pin headers (2.54 mm) with GPIO, SPI, UART, ADC, and power pins
  • Reset and Flash Buttons – On-board buttons for easy firmware flashing

Specifications

  • Chip – ESP8266 (ESP-12E module)
  • USB Bridge – CP2102
  • Power – 5 V via micro USB
  • Dimensions – 49 × 24.5 × 13 mm
Tip: Use a high-quality USB cable capable of supplying sufficient current. Low-quality cables may prevent the board from being recognised by your computer.

Ideal For

  • IoT and Wi-Fi connected projects
  • Home automation and sensor networks
  • Rapid prototyping with Arduino IDE or Lua
  • Learning ESP8266 development
