DC motor driver that allows you to control the movement of two drives using the I2C interface. Board with connectors for assembly. Pololu 5052

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

Two-channel driver for DC motors with an operating voltage from 7 to 35 V and a continuous current up to 10 A. It can be controlled by an analog signal, PWM, UART, RC or by means of built-in buttons. Cytron MDDS10

An H-bridge driver that provides bidirectional control of a high-power DC motor with a voltage range of 5-60 V and a continuous current of up to 11 A. The module supports PWM signals up to 100 kHz, features a current measurement (CS) output based on the ACS711 sensor, and features reverse polarity and short-circuit protection. It is compatible with both 3.3 V and 5 V logic, enabling easy integration with popular microcontroller platforms. Ideal for robotics, automation, and DIY projects requiring high performance and reliability. Pololu 2993

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
