NodeMCU Dev Kit with ESP8266, WiFi and AA Battery Holder

The development board is based on the WiFi-SoC ESP8266 and is made for fast Internet-of-Things (IoT) prototyping.

It is equipped with a light sensor, a RGB-LED and six red SMD-LEDs, which all can be accessed directly by you. Moreover, it can be powered by three AA mignon batteries. 

It is flashed with the latest firmware version and can be set up and programmed right away with a serial connection. With only few lines of code the NodeMCU Dev Kit is connected to your local network and ready to be controlled by other network members like computers and smartphones.

Check out the sample Lua commands on the official GitHub page.
