L293D Shield with NodeMCU ESP8266

odeMCU 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 NodeMCU. Besides Arduino IDE or Arduino programming langauge, NodeMCU supports many other languages like LUA script, microPython etc. With these scripting languages, you can develop your prototype within a few script lines. This shield is designed for the NodeMCU 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.
