Motor Driver Shield L293D for NodeMCU ESP-12E ESP8266

This shield is designed for the NodeMCU, 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.
