NodeMCU ESP8266 Base Interface Board for CH340 Version Price in Sri Lanka

Speed up your Internet of Things (IoT) application development process. NodeMCU is an open-source firmware that helps you prototype your IOT product with code like Arduino, but interactively in a Lua script.

The NodeMCU Development Board is based on the ESP8266 and integrates GPIO, PWM, IIC, 1-Wire, and ADC all on one board. You can use it to create your own WiFi hotspot, WiFi client, WiFi server, mesh network, two-way communications module, and more.

The expansion board base is designed to work with the NodeMCU Development Board ESP8266. Powered by 6V to 9V DC input, it provides the support power to operate the NodeMCU ESP8266 V3 development board, and provides easy connection to all of its input and output pins to help you connect your NodeMCU board to other devices.
