What it does

The NodeMCU ESP8266 V3 Lua WiFi Development Board (CH340) is a compact and cost-effective WiFi module perfect for IoT applications. With built-in TCP/IP protocol stack, it can connect microcontrollers to WiFi networks seamlessly.

Key features

  • 802.11 b/g/n WiFi with integrated TCP/IP stack
  • Low power consumption with deep sleep modes
  • Multiple GPIO pins with PWM, I2C, SPI support
  • Full Arduino IDE support with ESP8266 core
  • Lua scripting support via NodeMCU firmware
  • CH340 USB for programming and power
  • 4MB flash memory for application storage

Good to know

  • All GPIO operate at 3.3V – do not connect 5V signals directly
  • GPIO0 must be LOW during boot for programming mode
  • Install ESP8266 board package in Arduino IDE
  • Limited ADC (single channel) – use external ADC for multiple analog
  • WiFi and ADC cannot operate simultaneously on some pins
