ESP12E L293D NodeMcu Motor Driver Shield [4.5V-36V]

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 to the motor and the control board. The module is based on an ESP-12E development kit, integrates GPIO, PWM, IIC, 1-Wire and ADC all in one board. It provides 4.5V-36V DC voltage for motor and 4.5V-9V DC voltage to ESP control board. 
It can be added and completed by ESP8266 Wi-Fi Motor Drive Expansion module. For this purpose, note that  the antenna sign on the L293D module is a guide for direction of ESP8266 board, which this sign must be placed under the ESP8266 printed antenna.
