Module with TB6612FNG DC motors dual driver. The board is equipped with a Grove connector and communicates via the I2C interface. Seeed Studio 108020103

Simple to use stepper motor driver, compatible with anything that can output a digital 0..5V pulse or 0..3.3V pulse. Connect a 4-wire stepper motor and a microcontroller and you’ve got precision motor control! EasyDriver drives bi-polar motors, and motors wired as bi-polar. I.e. 4,6, or 8 wire stepper motors. ROB-12779

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 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

Pololu High-Power Motor Driver 24v20

A single-channel DC motor controller with a UART TTL interface. It is powered from 1.8 V to 22 V and can deliver up to 1.8 A of current. Board with connectors for assembly. Pololu 5077

Module with a single-channel driver of DC motors VNH2SP30. It allows you to control a DC motor with a supply voltage of up to 16 V and a current consumption of up to 30 A. Mini Monster Moto Driver

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 1362

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

The pad for use with shallow Feather series contains two TB6612 chips that allow you to control DC motors or stepper motors. The I2C interface is used to communicate with the overlay. Adafruit 2927

Regulator for DC brush motors, 10A, built-in BEC 1A, RoHS

Stepper motor driver based on TB67S249FTG. It allows you to control a stepper motor with voltage from 10 to 47V, with a maximum current of 1.8A. The controller can be controlled using: USB, Serial TTL, I2C, RC (PWM modeling), analog input or quadrature encoder. Pololu 3138

DC motor driver that allows you to control the movement of two drives using the I2C interface. Board without connectors. Pololu 5044

The X-NUCLEO-IHM17M1 is a low voltage three-phase brushless DC motor driver expansion board based on the STSPIN233 for STM32 Nucleo. It provides an affordable and easy-to-use solution for the implementation of portable motor driving applications such as thermal printers, robotics and toys

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.

TB9051FTG Single Brushed The DC Motor Driver Carrier is a single DC motor driver that allows the motor to be supplied with voltage in the 4.5 ... 28V range and power consumption at a continuous 2.6 A (5A peak) operation. Pololu 2997
