Pololu Dual G2 High-Power Motor Driver 24v18 for Raspberry Pi (Partial Kit)

Description

This add-on board makes it easy to control two high-power DC motors with a Raspberry Pi. Its twin discrete MOSFET H-bridges support a wide 6.5 V to 36 V operating range and are efficient enough to deliver a continuous 18 A without a heat sink. The drivers offer basic current limiting functionality, and they accept ultrasonic PWM frequencies for quieter operation. The default pin mappings make it easy to get started, but they can be customized for more specialized applications. This version ships as a partial kit; all surface-mount components are installed, but the included through-hole connectors are not soldered in.

PWM operation up to 100 kHz
Motor indicator LEDs show what the outputs are doing even when no motor is connected
Integrated 5 V, 2.5 A switching step-down voltage regulator powers the Raspberry Pi base for single-supply operation
Python library makes it easy to get started using this board as a motor driver expansion board
GPIO pin mappings can be customized if the default mappings are not convenient
Current sensing and limiting pins are exposed for advanced use
Reverse-voltage protection
Undervoltage shutdown
Short circuit protection
Operating voltage: 6.5 V to 36 V (absolute maximum; not intended for use with 24 V batteries)

Maximum can be increased to 40 V if regulator is disconnected (see below)

Output current: 18 A continuous
Active current limiting (chopping) with approximate default threshold of 50 A (can be adjusted lower)

The following through-hole connectors and mounting hardware are included with the board, which ships with its surface-mount components populated:

one 2×20-pin 0.1? female header
three 2-pin 5 mm terminal blocks
four M2.5 standoffs (11 mm length), screws, and nuts
