 The A4983 stepper motor driver carrier with voltage regulators is a breakout board for Allegro’s easy-to-use A4983 microstepping bipolar stepper motor driver. The board has two voltage regulators (5 V and 3.3 V), eliminating the need for separate logic and motor supplies. The driver features adjustable current limiting and five different microstep resolutions.

 The VNH2SP30 is an improved version of the VN3HSP30 motor driver, featuring current sensing, increased drive capability, and a higher maximum PWM frequency of 20 kHz.

 The VNH3SP30 is a great H-bridge motor driver for motors running from 6-16 V and drawing up to about 15 A. The chip is able to withstand 40-V transients, has a peak current of 30 A, and features various fault protection features such as over-temperature and over-current shutdown. For a higher-output version, see the VN2HSP30.

 This TI SN754410 motor driver is a quadruple half-H driver that can be used for bidirectional control of two DC motors or to control a single stepper motor. It is the same motor driver used in our dual serial motor controller.

 The L298 is a dual H-bridge driver for DC brushed motors and stepper motors. It supports a wide operating voltage range and can deliver 2 A per channel in a through-hole package that is accessible for do-it-yourself projects.

The Sanyo LB1836M is a great low-voltage dual motor driver (dual H-bridge) that we use in our micro dual serial motor controller and original Orangutan robot controllers. The low-voltage operation and relatively high peak current of 1 A make it an attractive option for those wanting to build small motion control systems powered by one or two Li-based cells or a few NiMH cells. 

 Need more current? If you’ve got a larger motor waiting to be used, this compact VNH2SP30 motor driver is just what you need. The VNH2 version includes current sensing and can operate a higher PWM frequency (20 KHz) than its VNH3 counterpart.
