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

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

The high power motor driver module works on the basis of Infineon BTS7960B systems. Maximum controller current: 43 A, operating voltage range: 5.5V - 27V. The module has a heat sink and can be controlled from the Arduino, Raspberry Pi, and STM levels. IBT_2

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

Direct current motor driver (DC) with a working voltage from 5 to 30 V and a maximum continuous current of 30 A. It can be controlled by a PWM signal or by means of built-in buttons. Cytron MD30C

The Tic T825 USB Multi-Interface Stepper Motor Controller makes basic control of a stepper motor easy, with quick configuration over USB using our free software. The controller supports six control interfaces: USB, TTL serial, I²C, analog voltage (potentiometer), quadrature encoder, and hobby radio control (RC).
