✍ This shield board is driven by the special large power full-bridge chip L293DD which can directly drive 2-channels DC motors or one-channel stepper motor. The driven current can be arrived at 1.2A. In this motor shield board, the IO port of ESP-12E Dev Kit is used as the control port. The logic chip configured inside can finish IC driven. Thus, the shield board has four ports: D1, D2, D3, and D3, which are used as PWMA(motor A), PWMB (motor B), DA (direction of motor A), and DB (direction of motor B), respectively.

✍ In addition, this shield board has many pins, such as VIN, 3.3V, DIO, AIO, SDIO, UART, SPI, RST, and EN, thus can conveniently connect all kinds of sensors (e.g., temperature and humidy, buzzer, light, relay sensor, etc.).

✍ The board is developed by the humanized design with a power switch, and thus user can control the on-off of power conveniently.
