A4990 Dual Motor Driver Carrier

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

Two-channel driver of direct current (DC) motors with an operating voltage from 6 to 30 V and a maximum continuous current of 20 A. It can be controlled by a PWM signal or by means of built-in buttons. Cytron MDD20A

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

Shield with dual-channel DC motor driver for Arduino. It has an operating voltage from 7 to 30 V and a continuous current of up to 10 A. It can be controlled by a PWM signal or by means of built-in buttons. Cytron SHIELD-MDD10

This is a breakout board for ON Semiconductor’s AMIS-30543 microstepping bipolar stepper motor driver, which features SPI-adjustable current limiting, 11 step modes (from full-step through 1/128-step), back-EMF feedback that can be used for stall detection or optional closed-loop control, and over-current and over-temperature protection. 

The RoboClaw Solo motor controllers from Basicmicro (formerly Ion Motion Control) can control a single brushed DC motor using USB serial, TTL serial, RC, or analog inputs. An integrated quadrature decoder make it easy to create a closed-loop speed control system.
