Stepper Motor Driver DRV8825
Stepper drivers capable of driving up to 2.5A per coil, with adjustable current and up to 32x microstepping.
DRV8825 drivers give you a nice performance edge over the more common A4988 drivers with cooler operation while producing less noise (whine). They have higher maximum current, and the ability to drive larger motors.
The stepper drivers come complete with heatsinks and adhesive to keep your stepper drivers cool while in operation.
