which was close to the limit of what would fit through the mounting holes

These modules are great for use with Arduinos or other microcontrollers

LiPo cells 1-4 N

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
