Alternative Closed-Loop Drivers

CLN17 is not the only closed-loop motor driver. There are several alternatives available, which are also closed-loop drivers and designed with a similar architecture. These drivers comprise a microcontroller, an encoder, and a driver, all integrated onto a single printed circuit board placed at the rear side of the NEMA17 motor.

Quick overview of the alternatives
