Product description

? Relative 4988 Features Benefits:
1. the maximum current of 2.5A.
2. up to 32 segments.
3. 4-layer PCB, better heat dissipation.
4. the chip resistance is smaller, less heat, and better heat dissipation.

? Parameters:
1. Size: 1.5mmX2mm (and the same 4988)
2. Can drive currents: 2.5A
3. Segmentation: 1,1 / 2,1 / 4,1 / 8,1 / 16,1 / 32
4. Manufacturing Process: SMT placement machine higher manufacturing, non-manual welding, yield more stable performance

? Suitable for:
1. Need to drive stepper motors.
2. It is to build a 3d printer, cnc, engraving machine and other essential modules.
3. Supported 3d printers have Prusa Mendel, ultimaker, printbot, makerbot like.
4. You can refer back Arduino code, direct drive motor

? DRV8825 features are the following:
1, suitable for driving below 8.2V ~ 45V 2.5A stepping motor;
2, only a simple step and direction control interface;
3, six different stepping modes: full, half, 1 / 4,1 / 8,1 / 16,1 / 32;
4, adjustable potentiometer can adjust the maximum current output, 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.
