Specification:
1)*Suitable for driving below 8.2V ~ 45V 2.5A stepper motor
2)*Six different stepping resolutions: full, half, 1 / 4,1 / 8,1 / 16,1 / 32.
3)*A simple steps and direction control interface.
4)*Adjustable potentiometer can adjust the maximum output current, resulting in higher step rate.
5)*Automatic current decay mode detection / selection.
6)*Thermal shutdown circuit, undervoltage lockout, crossover current protection.
7)*Ground short-circuit protection and load short-circuit protection.
8)*DRV8825:20*15*11mm/approx 0.79*0.59*0.43inch(L-W-H) .
9)*Heat Sink: 9*9*5mm/approx 0.35*0.35*0.2inch(L-W-H).
10)*Net weight: 4g/approx 0.008oz./pcs.
Note： Vref voltage must be less than 1.25V
