## Description

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 Resources NodeMCU DevKit – Hardware Schematics & PCB Layout (GitHub) NodeMCU Firmware Source Code (GitHub) NodeMCU Flasher – Windows Firmware Tool (GitHub) Flashing NodeMCU Firmware on Linux (Guide) CP210x USB-to-UART Bridge Drivers (Silicon Labs)
