1. The maximum current is 2.5A.
2. Up to 32 subdivisions are supported.
3. 4-layer PCB board, better heat dissipation performance.
4. The chip has lower internal resistance, lower heat generation and better heat dissipation.
parameter:
Size: 1.5mmX2mm (same as 4988)
Driven 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:
Where the stepper motor needs to be driven.
It is a necessary module for building 3d printer, cnc, engraving machine and so on.
Supported 3D printers include Prusa Mendel, ultimaker, printbot, makerbot, etc.
You can refer to the following Ardu code to directly drive the motor
DRV8825 features the following points:
1. Suitable for driving stepper motor below 8.2V ~ 45V 2.5A;
2. Only simple step and direction control interface;
3. Six different stepping modes: full, half, 1/4, 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 / selection;
6. Overheat shutdown circuit, undervoltage lockout, cross current protection;
7. Ground short circuit protection and load short circuit protection
