This shield makes it easy to control two high-power DC motors with your Arduino or Arduino-compatible board. Its twin discrete MOSFET H-bridges support a wide 6.5 V to 40 V operating range and are efficient enough to deliver a continuous 14 A without a heat sink. The drivers offer basic current sensing and current limiting functionality, and they accept ultrasonic PWM frequencies for quieter operation. The Arduino pin mappings can all be customized if the defaults are not convenient, and the motor driver control lines are broken out along the left side of the shield for general-purpose use without an Arduino.

Operating voltage: 6.5 V to 40 V (absolute maximum; not intended for use with 36 V batteries)
Output current: 14 A continuous
Current sense output proportional to motor current (approx. 20 mV/A; only active while H-bridge is driving)
Active current limiting (chopping) with approximate default threshold of 40 A (can be adjusted lower)

This version, the 24v14 motor driver shield, can be distinguished from the other versions by its blue PCB and the number 100 on top of the tall silver electrolytic capacitors.

General specifications

Motor channels: 2
Minimum operating voltage: 6.5 V
Maximum operating voltage: 40 V. Absolute maximum; higher voltages can permanently destroy the motor driver. Recommended maximum is approximately 34 V, which leaves a safety margin for ripple voltage on the supply line.
Continuous output current per channel: 14 A. Typical results at room temperature with both channels running at 90% duty cycle.
Current sense: 0.020 V/A
Maximum PWM frequency: 100 kHz
Minimum logic voltage: 1.8 V
Maximum logic voltage: 5.5 V
Reverse voltage protection?: Y
