Stepper motor driver DRV8825 with Micro-stepping capability. The module has a pinout that is identical to A4988 driver, yet it affoards better performance. Both drivers are compatible with the RAMPS shield for 3D printers and CNC.
The DRV8825 features adjustable current limiting, overcurrent, and overtemperature protection, and six microstep resolutions (down to 1/32-step). It can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (it is rated for 2.5 A per coil with sufficient additional cooling).
The driver requires a logic supply voltage (3 - 5.5 V) to be connected across the VDD and GND pins and a motor supply voltage (8 - 45 V) to be connected across VMOT and GND. The logic voltage can be supplied from an external source, such as that powering the logic of the rest of the system
Feature
4988 Features and Advantages
1, high current 2.5A.
2, high support 32 subdivisions.
3, 4 layer PCB board, better heat dissipation performance.
4, the chip internal resistance is smaller, lower heat, better heat dissipation.
Parameters
Size: 15mmX20mm (same as 4988)
Driving current: 2.5A
Subdivision: 1, 1/2, 1/4, 1/4, 1/8, 1/16, 1/32
Manufacturing process: SMT mechanism, non-manual welding, higher yield, more stable performance
Application
Where a stepper motor needs to be driven.
It is an essential module for building 3d printers, cnc, engraving machines, etc.
Support 3 d printers have Prusa Mendel, ultimaker, printbot, makerbot, etc.
The DRV8825 features the following:
1, suitable for driving 8.2V~45V 2.5A stepper motor below;
2, only 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, so as to obtain a higher step rate;
5, automatic current attenuation mode detection/selection;
6. Overheat closing circuit, undervoltage locking, cross current protection;
7, grounding short-circuit protection and loading short-circuit protection
