      L293D Motor Driven Expansion Board for NodeMcu Lua Wifi Board (ER-DPO17021B)

      This is the first motor-driven expansion board that based on ESP- 12E development platform. When inserting ESP-12E module, please note the direction consistent with an expansion board antenna; The use of short modules that can simultaneously control board and motor.

      Features

      • ESP12 DEV KIT development board expansion module;
      • lead ESP12 DEV KIT all the features of pins: SPI, UART, GPIO, AI and 3.3V power connector;
      • extend two-way motor-driven, two-way direct drive motor;
      • onboard power switch;
      • L293D
      • Motor power, control power separation; In the experiment, a short circuit can block the merger, shorted to VIN and VM, while power supply to the motor and the control board.
