Motor shield for ESP-12E This is the first motor shield for ESP8266 based on ESP-12E and It is very convenient and cheap to diy a WiFi controllable motors , DC motors, stepper motors, servo motor.. etc. using ESP-12 DEV KIT development shield module; extend the output ports for ESP-12 DEVKIT: SPI, UART, GPIO, AI and 3.3V power interface; extend 2-ways motor, then can directly drive 2-ways motor; design a power switch; driven chip: L293D; voltage for motor: 4.5V-36V; voltage for ESP control board: 4.5V-9V; disparate the power of ESP board and motor for avoiding the interference. In our experiments, for convenience, a shortcut module is used to connect VIN and VM for the power of ESP board and motor.
