Node MCU is an open-source development board, based on famous ESP8266 chip (ESP12E or ESP12F), which is a 32-bit controller with integrated WIFI transceiver. And it is very low cost. Best of all, this board is Arduino IDE compatible, you can utilize the millions of example codes and libraries on Node MCU. Besides Arduino IDE or Arduino programming langauge, Node MCU supports many other languages like LUA script, micro Python etc. With these scripting languages, you can develop your prototype within a few script lines.
This shield is designed for the Node MCU V2 (narrow width), it comes with L293D motor driver and breakout the GPIO to headers for easy access when connecting to various sensor modules. With the L293D, this shield supports the control of two (2) brush motor, start, stop, brake, direction and also speed. The shield also extends the GPIO of NodeMCU to header pins in SVG sequence (RC servo alike), not to forget the UART , SPI, Power and GND pins. There are options to power the board separately or with single power source. The board also comes with a power LED indicator and latching push button as power switch.
This shield is very convenient and cheap to build or DIY a WIFI RC smart car or any type of robotics or even UAV platform.
Note: Compatible with narrow width Node MCU, get it from here. NOT compatible with Node MCU V3 (wider width)
