Pololu G2 High Power Motor Driver 18A, 6.5V-40V- 24v18

• Operating voltage: 6.5 V to 40 V (absolute maximum)
• Output current: 18 A continuous
• Inputs compatible with 1.8 V, 3.3 V, and 5 V logic
• PWM operation up to 100 kHz

The Pololu G2 High Power Motor Driver 18A, 6.5V-40V- 24v18 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 18 A without a heat sink. The driver offers basic current sensing and current limiting functionality, and it accepts 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. 

Features

• Arduino shield form factor: The G2 can be plugged directly into an Arduino or compatible board, such as the A-Star 32U4 Prime
• The minimum operating voltage is 6.5 V
• Features an integrated 7.5 V, 1 A switching step-down regulator that can optionally be used to power whatever Arduino or Arduino-compatible board it is plugged into
• Operation from a single power supply
• This regulator can also be configured to output 5 V for applications where that would be more useful than the default 7.5 V, and the Arduino pin mappings can all be customized if the defaults are not convenient
