Features:

          1. the maximum current of 2.5A.

          2. the maximum support 32 subdivision.

          3. 4 layer PCB board, better heat dissipation.

          4. the chip resistance is smaller, lower heat, better heat dissipation.

parameter:

     Size: 1.5mmX2mm (same as 4988)

     Drive current: 2.5A

     Subdivision: 1,1 / 2,1 / 4,1 / 8,1 / 16,1 / 32

     Manufacturing process: SMT placement machine manufacturing, non-manual welding, higher yield, more stable performance

Suitable for:

     Need to drive stepper motor occasions.

     Is to build 3d printer, cnc, engraving machine and other essential modules.

     Supported 3d printers are Prusa Mendel, ultimaker, printbot, makerbot and so on.

     Refer to the Arduino code below to drive the motor directly

DRV8825 features have the following points:

1. suitable for driving 8.2V to 45V , 2.5A below the stepper motor;

2. only a simple step and direction control interface;

3. six different step modes: full, half, 1/4, 1/8, 1/16, 1/32;

4. adjustable potentiometer can adjust the maximum current output, in order to obtain a higher step rate;

5. automatic current attenuation mode detection / selection;

6. overheat shutdown circuit, undervoltage lockout, cross current protection;

7. ground short circuit protection and load short circuit protection.
