DC motor driver that allows you to control the movement of two drives using the I2C interface. Board with soldered connectors. Pololu 5048

Single-channel DC motor driver with an operating voltage from 10 to 45 V and a continuous current up to 40 A. It can be controlled by an analog signal, PWM, UART, RC or by means of built-in buttons. Cytron MDS40B

DC motor driver that allows you to control the movement of two drives using the I2C interface. Board with soldered connectors. Pololu 5036

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

Atmel ATmega32U4 microcontroller comes preloaded with an Arduino-compatible bootloader, and the board includes dual motor drivers that can deliver 1.7 A per channel to two brushed DC motors. Pololu 3119

DRV8801 Single Brushed DC Motor Driver Carrier

HAT with TB6612FNG engine controller and PCA9685 PWM controller designed for Raspberry Pi minicomputers. The board is equipped with a 40-pin connector characteristic of Raspberry Pi, making it compatible with all minicomputers with this connector. Waveshare Motor Driver HAT

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

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 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.
