Motoron M1U550 Single Serial Motor Controller - DC motor controller (assembled)

DC motor driver with voltage 6.5..40V and maximum continuous current 21A. It has the ability to easily implement the feedback loop and numerous control interfaces. Polol 3149

Tiny breakout board for TI’s DRV8838 motor driver can deliver a continuous 1.7 A (1.8 A peak) to a single brushed DC motor. Operating voltage range from 0 V to 11 V, built-in protection against reverse-voltage, under-voltage, over-current, and over-temperature. Pololu 2990

Pololu High-Power Motor Driver 24v23 CS

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

Two-channel driver of direct current (DC) motors with an operating voltage from 4 to 16 V and a maximum continuous current of 3 A. It can be controlled by a PWM signal or by means of built-in buttons. Cytron MDD3A

DC motor driver that allows you to control the movement of two drives using the I2C interface. Board with soldered connectors. Pololu 5042

This compact expansion board plugs directly into the GPIO header on a Raspberry Pi B+, A+, or Pi 2 and provides an easy and low-cost solution for driving a pair of small brushed DC motors. Pololu 2753

A single-channel DC motor driver with an I2C interface. It is powered from 4.5 V to 48 V and can deliver up to 2.2 A of current. A board with soldered connectors. Pololu 5060

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 30 Voperating 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 RoboClaw Solo motor controllers from Basicmicro (formerly Ion Motion Control) can control a single brushed DC motor using USB serial, TTL serial, RC, or analog inputs. Pololu 3291

An H-bridge capable of controlling one DC motor in both directions or two unidirectional motors at voltages from 4.5 to 44 V and continuous currents up to 1.3 A. The module offers three operating modes (PH/EN, IN/IN, half-bridge), built-in current limiting and measurement, and protection against overheating, overload, undervoltage, and reverse polarity. Its compact design, flexible logic power supply (1.8–5.5 V), and simple control make it ideal for robotics, automation, and hobby projects. Pololu 4971

DC motor driver that allows you to control the movement of three drives using the I2C interface. Plate with connectors for assembly. Pololu 5031

Dual DC motor controller with voltage from 2.5 to 9.5V with 1A continuous current per channel. Has an embedded voltage regulator. Cytron Maker Drive

This discrete MOSFET H-bridge motor driver enables bidirectional control of one high-power DC brushed motor. The small 1.3″ × 0.8″ board supports a wide 6.5 V to 30 V voltage range and is efficient enough to deliver a continuous 25 A without a heat sink.

Module with DC motor driver DRV8256P. It can work with motors supplied with the voltage from 4.5 to 48 V and the current consumption up to 1.9 A. Pololu 4039
