Motor Drivers

This page describes the different motor controllers that OSURC Members have experience with and would suggest for use in projectrs.

Stepper Motors

These are higher torque motors that are characterized typically due to their accuracy (ex: 1 “step” is always 1.8deg) generally.

L298N Motor Drivers

These little H-bridge drivers are fantastic for controlling small motors or steppers using PWM. The best part is that they are phenomenally cheap; you can typically get 10 L298N modules for around $20 or sometimes cheaper from sites like eBay, AliExpress, Banggood, and others. These drivers claim they can handle up to 3.5 amps, but you should keep it below 2. A single L298N module can control 2 DC motors or one stepper.

DRV 8825 Driver

This is a very easy to use stepper motor driver.

Available on Pololu , $8.95 at time of writing

Brushed DC Motors

Sabertooth Motor Drivers Saberteeth are relatively-solid motor controllers that can be controlled using Serial or PWM.

Sabertooth 2x25 2 25A channels

L298N Motor Drivers

These little H-bridge drivers are fantastic for controlling small motors or steppers using PWM. The best part is that they are phenomenally cheap; you can typically get 10 L298N modules for around $20 or sometimes cheaper from sites like eBay, AliExpress, Banggood, and others. These drivers claim they can handle up to 3.5 amps, but you should keep it below 2. A single L298N module can control 2 DC motors or one stepper.

BTS7960 (aka IBT_2) Motor Drivers

These are 43 amp half-bridge modules that are cheap, small, and fun to use. They are really great for Arduino projects where you need to control a torquier-than-average motor with PWM. Like the L298N, you can get these from eBay, or AliExpress. They are a little more expensive than the L298N (usually about 10 bucks), but they are unbeatable if need a little more oomph than what the L298N is capable of.

Brushless Motors

These are motors that are typically “faster” (more RPMs) and lower torque than others.
