(3). DRV8825 Stepper Motor Driver with Heatsink
Product Description
The DRV8825 stepper motor driver module has a pinout that is almost
identical to the interface and the A4988 stepper motor carrier, so it
can be used as a higher performance replacement in many applications.
DRV8825 has adjustable current limit, overcurrent and thermal
protection, 6 micro resolutions (1, 1/2, 1/4, 1/8, 1/16, 1/32). It uses
8.2-45V and can provide Up to about 1.5 per phase or forced air flow
(rated up to 2.2 per roll with sufficient additional cooling).
