ESP-12E Motor Shield is designed and developed by Shenzhen Doctors of Intelligence & Technology (SZDOIT). This large current motor driven module can compatible with ESP12E Dev Kit and NodeMCU.By using the overlap-plug design, the motor shield can be directly plugged by ESP-12E Dev Kit and NodeMCU Lua module.
This shield board is driven by the special excent large power full-bridge chip L293DD from the famous Stmicroelectronics company, which can directly drive 2-channels DC motors or one-channel stepper motor. The driven current can be arrived at 1.2A. This board is generated with national layout, SMT ensuption, and convenient installation.
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.
