ESP8266 NodeMcu Lua WIFI V3 Development Board CH340 - Ultimate IoT Solution

SKU	ELE-COM-127
Weight	10 g
Ships from	Cardiff, UK

The ESP8266 NodeMCU development board is a compact, Wi-Fi-enabled microcontroller ideal for IoT projects, home automation, and rapid prototyping with Arduino IDE or Lua scripting.

This ESP8266 NodeMCU development board pairs the powerful ESP8266 Wi-Fi SoC with a CH340 USB-to-serial converter (a common USB bridge chip), giving you reliable one-cable programming from any PC or Mac. In addition, the breadboard-friendly pin layout and 3.3 V–5 V input range let you connect sensors, relays, and peripherals straight away. Making it one of the most cost-effective platforms for connected maker projects.

Key Features of the ESP8266 NodeMCU Development Board

• ESP8266 Wi-Fi SoC with 802.11 b/g/n — 2.4 GHz wireless connectivity
• CH340 USB-to-serial chip for straightforward programming on Windows, Mac, and Linux
• Supports Arduino IDE, MicroPython, and Lua (NodeMCU firmware)
