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

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

DC motor driver with voltage 6.5 ... 40V and maximum continuous current 13A. It has the ability to easily implement the feedback loop and numerous control interfaces. Polol 3147

This powerful motor controller makes closed-loop speed or position (but not both!) control of a brushed DC motor easy, with quick configuration over USB using our free software. It supports five control interfaces: USB, TTL serial, I²C, analog voltage (potentiometer), and hobby radio control (RC).

Dual MAX14870 Motor Driver is a dual DC driver compatible with Raspberry Pi that allows you to control two DC motors with 4.5-36V continuous current of 1.7A. Pololu 3759

2x1.2A DC Motor Driver is a dual controller of DC motors with a Gravity connector, supplied with 2.5 ... 12V voltage with a maximum current consumption of 1.2A (3.2A peak) per channel. DFRobot DRI0044-A

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. 

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

The RoboClaw motor controller can control a pair of brushed DC motors using USB serial, TTL serial, RC or analog inputs. Integrated dual quadrature decoders make it easy to create a closed-loop speed control system. This version can supply a continuous 7.5 A per channel (15 A peak). Pololu 3284
