These modules are great for use with Arduinos or other microcontrollers

the SCI DAQ Module already supports over 20 popular sensors

This driver is also available as Dual MAX14870 motor driver shield for Arduino and a Dual MAX14870 motor driver kit for the Raspberry Pi to make it easy to incorporate into a two-motor application

Pololu Dual G2 High-Power Motor Driver 18v22 Shield for Arduino Shipping:2-4 Weeks which was close to theThis 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 30 V operating range and are efficient enough to deliver a continuous 22 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
