16-channel servo driver HAT (B) module for Raspberry Pi - Waveshare 17035

PiFace Relay Motor Control Extra (Board) for Raspberry Pi

Adafruit 16-Channel PWM / Servo HAT for Raspberry Pi - Mini Kit (Adafruit 2327)

Adafruit 2348

This programmable module combines with a Raspberry Pi to serve as the control center of a small robot or electronics project. Its Atmel ATmega32U4 microcontroller comes preloaded with an Arduino-compatible bootloader, and the board includes dual motor drivers that can deliver 1.8 A per channel to two brushed DC motors.

The core of a small robot, either as an auxiliary controller atop a Raspberry Pi base or as a complete control solution on its own. Its Atmel ATmega32U4 microcontroller comes preloaded with an Arduino-compatible bootloader. This version does not include any through-hole components or connectors, allowing for customized assembly or standalone use. Pololu 3118

This add-on board enables a Raspberry Pi B+, Pi A+, Pi 2 or Pi 3 to drive a pair of brushed DC motors. Its dual MC33926 motor drivers operate from 5 V to 28 V and can deliver a continuous 3 A (5 A peak) per motor. The default pin mappings make it easy to get started using our provided software, but the board also exposes most of the driver chips’ I/O pins for more specialized applications. 

Raspberry Pi Expansion Board, DC Motor / Stepper Motor Driver

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 Voperating range and are efficient enough to deliver a continuous 14 A without a heat sink. The drivers offer basic current limiting functionality, and they accept ultrasonic PWM frequencies for quieter operation.

HAT module with a driver for two DC motors designed for Raspberry Pi. Motors can be powered with the voltage from 6.5 to 30 V and draw a maximum current of up to 18 A. Pololu 3751
