WEMOS D1 Mini compatible Motor Driver Shield

The motor driver shield for the D1 Mini and compatible modules communicate through the I2C bus with the MCU, which only requires 2 GPIO ports.

• I2C interface
• Power supply voltage: VM=15V max
• Output current: Iout=1.2A(average) / 3.2A (peak)
• Standby control to save power
• CW/CCW/short brake/stop motor control modes

Pin description:

• VM: Motor power supply + (Max 15Vdc)
• GND: Motor power supply –
• A1 A2: Motor A
• B1 B2: Motor B
• S: Standby control port (in IO mode)
• Standby control mode
  • I2C mode: Control TB6612s STBY with I2C protocol
  • IO mode: Control TB6612s STBY with S pin
• Shield reset mode
  • short: reset with d1 mini (reset at power on or press d1 minis reset button)
  • open: reset by DTR pin.
