Adafruit Motor/Stepper/Servo Shield v2
Arduino shield for driving up to 4 DC motors or 2 stepper motors and 2 servos. Features two TB6612 MOSFET H-bridge drivers (1.2A continuous, 3A peak per channel) and a PCA9685 16-channel PWM driver (12-bit, I2C interface) for motor speed control and servo control. Operates from 4.5–13.5 V motor supply, logic level configurable via Arduino IOREF (5V by default). Includes polarity-protected external power terminal, reset button breakout, and stacking headers for address selection (up to 32 shields stackable for 64 steppers/128 DC motors total). Ideal for robotics projects requiring multiple motors and servos.
