Adafruit Motor/Stepper/Servo Shield for Arduino v2.3 Kit

Product Description

This kit has TB6612 MOSFET drivers with 1.2A per channel current capability (you can draw up to 3A peak for approx 20ms at a time). It also has much lower voltage drops across the motor so you get more torque out of your batteries, and there are built-in flyback diodes as well.

Instead of using a latch and the Arduino's PWM pins, this kit has a fully-dedicated PWM driver chip onboard. This chip handles all the motor and speed controls over I2C. Only two data pins (SDA & SCL in addition to the power pins GND & 5V) are required to drive the multiple motors, and since it's I2C you can also connect any other I2C devices or shields to the same pins. This also makes it drop-in compatible with any Arduino, such as the Uno, Due, Leonardo and Mega R3.

As well, it is a completely stackable design: 5 address-select pins means up to 32 stackable shield. That adds up to 64 steppers or 128 DC motors.
