NodeMcu ESP8266 CH340G Development Board

The NodeMcu ESP8266 CH340G Development Board is a popular IoT development platform that combines the ESP8266 WiFi module with a USB-to-serial converter based on the CH340G chip. This board is widely used for building IoT applications due to its low cost, ease of use, and strong community support. Here are the detailed specifications and features:


  • Microcontroller: ESP8266
  • Operating Voltage: 3.3V
  • Input Voltage (Vin): 4.5V to 10V (typically 5V via USB)
  • Digital I/O Pins: 11 (GPIOs)
  • Analog Input Pins: 1 (0V to 3.3V input range)
  • Flash Memory: 4MB (32Mb)
  • SRAM: 64KB
  • Clock Speed: 80MHz (can be overclocked to 160MHz)
  • USB to Serial Converter: CH340G
  • WiFi Standards: 802.11 b/g/n
  • Operating Current: Average 80mA
  • Dimensions: Typically around 50mm x 25mm x 13mm

Pin Configuration

  • Vin: External power supply (4.5V-10V)
  • 3V3: 3.3V output
  • GND: Ground
  • RST: Reset
  • EN: Chip enable (active high)
  • D0-D8: GPIO pins
  • A0: Analog input
  • TX: UART Transmit
  • RX: UART Receive


  • Built-in WiFi: Integrated 802.11 b/g/n WiFi transceiver with full TCP/IP stack and microcontroller capability.
  • USB to Serial Communication: CH340G USB-to-serial converter for easy programming and communication with a computer.
  • Compatibility: Compatible with the Arduino IDE, allowing for easy programming with Arduino libraries and tools.
  • Deep Sleep Mode: Supports deep sleep mode for low power consumption.
  • Breadboard-Friendly: The compact design and pin layout make it suitable for breadboard use.
  • Lua Scripting Support: Supports NodeMcu firmware for programming with Lua scripting language.

NodeMCU Development Board Pinout Configuration

Pin Category Name Description
Power Micro-USB, 3.3V, GND, Vin Micro-USB: NodeMCU can be powered through the USB port


3.3V: Regulated 3.3V can be supplied to this pin to power the board


GND: Ground pins


Vin: External Power Supply

Control Pins EN, RST The pin and the button resets the microcontroller
Analog Pin A0 Used to measure analog voltage in the range of 0-3.3V
GPIO Pins GPIO1 to GPIO16 NodeMCU has 16 general purpose input-output pins on its board
SPI Pins SD1, CMD, SD0, CLK NodeMCU has four pins available for SPI communication.
UART Pins TXD0, RXD0, TXD2, RXD2 NodeMCU has two UART interfaces, UART0 (RXD0 & TXD0) and UART1 (RXD1 & TXD1). UART1 is used to upload the firmware/program.
I2C Pins NodeMCU has I2C functionality support but due to the internal functionality of these pins, you have to find which pin is I2C.
