Description

ESP12E L293D NodeMcu Motor Driver Shield  is the first motor shield for ESP8266 based on ESP-12E which enable the designers simultaneously to drive and control DC motor with an Arduino. A motor controller is a necessary intermediate device between the robot's micro-controller, batteries and motors, because a micro-controller can usually just produce about 100 mili Amps of current, which is not adequate to drive most motors (DC motors, DC gear motors, servo motors and so on) which needs greater than one ampere currents.

By the module, It is very convenient and cheap to DIY a Wi-Fi RC smart car or IoT gadget. For avoiding the interference, it's better to have separate motor power supply and control power supply, so VIN and VM can be short-circuited, when the power supply Note:
