NodeMCU Motor Shield Board L293D for ESP-12E from ESP8266 esp 12E kit diy rc toy wifi rc smart car remote control

Based on the first motor-driven expansion board ESP-12E development. ESP12 DEV KIT development board expansion module;  lead ESP12 DEV KIT All-function pins: SPI, UART, GPIO, AI, and 3.3V power connector; expand two-way motor-driven, two-way direct drive motor;  onboard power switch;  L293D 

• ESP12 DEV KIT development board expansion module; lead ESP12 DEV KIT All-function pins: SPI, UART, GPIO, AI, and 3.3V power connector;

• expand two-way motor-driven, two-way direct drive motor; onboard power switch; L293D

• Motor power range: 4.5V ~ 36V; Control power range: 4.5V ~ 9V;

• Motor power, control power separation; In the experiment, by short-circuiting block, the merger, the VIN and VM short, while power supply to the motor and the control board.

• Motor Power (VM): 4.5V ~ 36V, can be a separate power supply; | Control power (VIN): 4.5V ~ 9V (10VMAX), can be powered separately; | Module provides short-circuit sub (short the VM and VIN), you can easily use one power (must 4.5V ~ 9V) simultaneously drive and control the motor; | Logic Operating current Iss: 60mA (Vi = L), 22mA (Vi = H);
