This small shield is an easy, economical way to control two small brushed DC motors with an Arduino or Arduino-compatible board. Its two integrated MAX14870 motor drivers allows it to operate from 4.5 V to 36 V, making it a great for higher-voltage motors and applications, and the shield can 1.7 A continuous (2.5 A peak) per motor. The shield can optionally be configured to power the Arduino from the same power supply as the motor driver, and the Arduino pin mappings can be customized (by cutting traces) if the defaults are not convenient.

Two single-channel H-bridge motor drivers with shoot-through protection and internal free-wheeling diodes (can each drive one DC motor)
Motor supply voltage: 4.5 V to 36 V
Output current: 1.7 A continuous (2.5 A peak) per motor
PWM operation up to 50 kHz (ultrasonic frequencies allow for quieter motor operation)
Simple two-pin DIR/PWM interface (one pin controls direction and another controls speed)
Shield can optionally power the Arduino base directly when motor supply voltage is suitable
Shield has convenient location for adding a 3-pin voltage regulator to power the Arduino base in applications where the motor supply voltage is not suitable for powering the Arduino directly
Arduino library makes it easy to get started using this board as a motor driver shield
Arduino pin mappings can be customized (by cutting traces) if the default mappings are not convenient
Reverse-voltage protection on motor power supply
Under-voltage lockout
Active-low fault output indicates over-current or over-temperature condition
Surface-mount resistors can optionally be added to enable automatic current limiting
