Motoron M1T256 Single I²C Motor Controller - DC motor controller (soldered)

DC motor driver that allows you to control the movement of two drives using the I2C interface. Board without connectors. Pololu 5038

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

Dual MC33926 Motor Driver CarrierTwo-channel DC motor controller with voltage from 5 V to 28 V, power consumption up to 3 A per channel. Controlled by PWM signal. Pololu 1213

This shield makes it easy to control two high-power DC motors with your Arduino or Arduino-compatible board. Its dual robust VNH5019 motor drivers operate from 5.5 to 24 V and can deliver a continuous 12 A (30 A peak) per motor, or a continuous 24 A (60 A peak) to a single motor connected to both channels. Pololu 2507

Module with DC motor driver DRV8874. It can work with motors supplied with the voltage from 4.5 to 37 V and current consumption up to 2.1 A. Pololu 4035

Dual DC motor controller designed for Raspberry Pi, which enables the engine to be supplied with voltage in the 4.5-28V range and power consumption in continuous operation of 2.6A (5A in peak) of two DC motors. Pololu 2762

A two-channel DC motor controller with a I2C interface. It is powered from 1.8 V to 22 V and can deliver up to 1.6 A per motor. Board with connectors for assembly. Pololu 5079

ESC RC controller module with FlySky receiver designed for two brush motors with a supply voltage from 2.5 to 5 V and a current consumption of 2 A

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 current up to 1.1 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 4972

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

Universal platform dedicated to Intel Edison modules. Designed for the construction of four-wheeled mobile robots. Seeed Studio 102010028

Pololu G2 18v15 High Power is a miniature DC motor controller. Power supply for the controller: 6.5 ... 30 V. Current efficiency of the module: 15 A. The module has protection against back voltage and overvoltages. Pololu 1363

This Kit with fully-dedicated PWM driver chip handles all the motor and speed controls over I2C. Only two data pins (SDA & SCL in addition to the power pins GND & 5V) are required to drive the multiple motors; you can also connect any other I2C devices or shields to the same pins. This  makes it drop-in compatible with any Arduino, such as the Uno, Due, Leonardo and Mega R3. Adafruit 1438

DC motor driver with a working voltage from 5 to 30 V and a maximum continuous current of 13 A. It can be controlled by a PWM signal or by means of built-in buttons. Cytron MD10C

Single-channel DC motor controller enabling motor control with voltage in the range of 7-30V and current up to 10A. The set has a potentiometer and a direction switch. Cytron MD10_POT

Module with DC motor driver DRV8876. It can work with motors supplied with the voltage from 4.5 to 37 V and current consumption up to 1.1 A. Pololu 4037
