RATTMMOTOR CNC Controller Kit CNC GRBL Shield Board V3 Expansion Board with 4pcs DRV8825 Stepper Motor Driver with Heatsink Compatible with Arduino IDE Sutitable for CNC Router Machine, 3D Printer

This expansion board and DRV8825 Stepper Motor Driver can be used as a drive expansion board for engraving machines, 3D printers, etc.

There are a total of 4 slots for stepper motor drive modules, which can drive 4 routes without motors, and each stepper motor only needs 2pcs IO port.

That is to say, 6pcs IO port can manage 3 stepping motors well, which is very convenient to use, bid farewell to the cumbersome operation of traditional stepping motors.

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).
