DRV8825 Stepper Motor Driver Carrier is a DRV8825 stepper motor driver that allows you to supply a bipolar current of up to 1.5 A per phase, without using a heat sink. The system can be supplied with voltage up to 45V, in the set there is a heat sink. Polol 2133

DRV8834 Low-Voltage Stepper Motor Driver Carrier

(DRI0009) 2A Motor Shield For Arduino

DRV8801 Single Brushed DC Motor Driver Carrier

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

Expansion board with L6474 stepper motor driver. It is equipped with a connector compatible with Arduino Uno R3 and STM32 Nucleo. STMicroelectronics X-NUCLEO-IHM01A1

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

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
