DRV8825Relative4988 Advantages:

1. maximum current2.5A。

2, top support32To subdivide.

3,4layerPCBBoard, better heat dissipation performance.

4The internal resistance of the chip is smaller, the heat is lower and the heat dissipation is better.

Parameters:

Size:1.5mmX2mm(and)4988Same)

Driving current:2.5A

To subdivide:1,1/2,1/4,1/8,1/16,1/32

Manufacturing process:SMTSMT machine manufacturing, non manual welding, higher yield, more stable performance

Suitable for:

Where stepper motors need to be driven.

Is building3dPrinter,cnc, engraving machine and other necessary modules.

Supportive3dPrinter hasPrusa Mendel,ultimaker,printbot,makerbotAnd so on.

1，Suitable for driving8.2V~45V 2.5AThe following stepper motors;

2， only simple step and direction control interface;

3，Six different step modes: full, half1/4,1/8,1/16,1/32;

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

5， automatic current attenuation mode detection/Choice;

6，Over temperature shutdown circuit, under voltage locking, cross current protection;

7，Grounding short circuit protection and loading short circuit protection
