Description
These stepper drivers are built around Allegro's A4988 stepper driver IC. This is one of the most common and widespread stepper driver ICs used in 3D printer electronics and is commonly selected because of its balance of performance, cost, and reliability.
These drivers are made in the Pololu-style 'stepstick' footprint. They are compatible with any control board that accepts this footprint, including RAMPS and RUMBA+. They come with the headers already soldered in place, and also come complete with a small heatsink, with adhesive already attached. Perfect!
