L293D WIFI MOTOR DRIVE EXPANSION BOARD

L293D Motor Driver module is compatible with ESP12E Dev Kit and NodeMCU. This shield board is driven by the power full-bridge chip L293DD which can directly drive 2-channels DC motors or one-channel stepper motor.

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 humidity, buzzer, light, relay sensor, etc.)

• • ESP8266 WiFi Motor Drive Expansion Shield Board For NodeMCU ESP-12E
  • Motor power supply (VM): 4.5V ~ 36V, can be powered separately
  • 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 be 4.5V ~ 9V) while completing motor drive and control.
