DRV8825 Stepper Motor Driver Board with Aluminum Heat Sink for 3D Printers

Description

1. Supply Voltage: 8.2 – 42 VDC.
2. Current Capacity : 2.2A max(24V).
3. Continuous current per phase: 1.5 A.
4. Minimum Logic voltage: 2.5V.
5. Maximum Logic Voltage: 5V.
6. Microstep resolutions: full, 1/2, 1/4, 1/8, 1/16, and 1/32.
7. Dimensions : 15 x 20 mm.
8. Weight: 4 gm.

Features :

1. Microstep resolutions: full, 1/2, 1/4, 1/8, 1/16, and 1/32.
2. Simple step and direction control interface
3. Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
4. Adjustable current control lets you set the maximum current output with a potentiometer. Hence lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
5. Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
6. 45 V maximum supply voltage
7. Built-in regulator (no external logic voltage supply needed)
8. Can interface directly with 3.3 V and 5 V systems
9. Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout
10. Short-to-ground and shorted-load protection
11. 4-layer, 2 oz copper PCB for improved heat dissipation
12. Exposed solderable ground pad below the driver IC on the bottom of the PCB
