D1 Mini motor shield designed for use with ESP8266 D1 Mini boards, providing dual DC motor control via the I2C bus. Based on the TB6612 driver, the shield requires only two GPIO pins from the MCU for control, making it suitable for compact WiFi-enabled robotics and automation projects.
- Communication: I2C interface (requires only 2 GPIOs)
- Motor driver: TB6612
- Motor supply voltage (VM): up to 15 V DC
- Output current: 1.2 A average, 3.2 A peak per channel
- Control modes: CW, CCW, short brake, stop
Standby control:
- I2C mode - TB6612 standby controlled via I2C protocol
- IO mode - standby controlled via S pin
Shield reset options:
- Short - reset together with D1 Mini (power-on or reset button)
- Open - reset by DTR pin
Pin assignments:
- VM: motor power supply + (max 15 V DC)
- GND: motor power supply -
- A1, A2: motor A outputs
- B1, B2: motor B outputs
- S: standby control port (IO mode)
Provides reliable dual motor control for compact IoT and WiFi-based applications using the D1 Mini platform.
