Arduino cnc shield and driver assembly. The power does not feed into the arduino so don t worry about frying it. Please note the potentiometer pot on a4988 and drv8825 are at the opposite side.
Important things to consider before you begin.
That does not mean that all pololu stepper drivers can run that high. Once you ve attached it you can fire up your favourite grbl controller software. The 36v are for drivers like the pololu drv8825 that can run on 36v. The big easy driver is a stepper motor driver board for bi polar stepper motors up to the basic wiring diagram is shown below in figure 3.
