MOT-DRV8825 DRV8825 3D Printer Stepper Driver Board

It is basically a DRV8825 stepper motor driver module that comes with a heatsink in a ESD safe bag. The features from the DRV8825 chips will offer you adjustable current limit, overcurrent and temperature protection with a six micro-resolution (1/32 step) feature. The module can handle from 8.2 - 45v. 


Simple step and direction control interface
The interface can connect directly with 3.3V and 5V systems
Support over-temperature thermal shutdown, over-current shutdown and under-voltage lockout
Support short-to-ground and shorted-load protection
Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
4-layer, 2 oz copper PCB for improved heat dissipation
Adjustable current control support you to set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
45V maximum supply voltage
Built-in regulator (needed external logic voltage supply)
