Wiring stepper motor to DRV8824 Stepper Motor Driver


I have 3 linear stages that are driven by Nema 08 stepper motors. I am trying to use 3 Pololu Low Current stepper motor drivers with the C10 bidirectional breakout board to control the motion using Mach3. From as far as i have understood i can connect the stepper motors connections to the Pololu board and then i would need to connect the pololu board to the c10 board.

I have a few questions regarding the wiring:
a). I would need to connect the four motor leads to A1 A2 B1 B2.
b). After this will i need to connect the Pololu drive to a power supply or will it be able to draw enough power from the C10 Bi directional breakout board - link for the board - cnc4pc.com/Store/osc/product … ucts_id=45
c). Also if i would need to connect the Pololu boards individually to a power supply, then how much voltage would i need to supply and which are the terminals on the board?
d). Also what connections would i need to take from the Pololu board to the C10 Breakout board? Will only the Step and Direction connection be enough?

Please forgive my questions, i have very little idea about this and trying to learn as much as possible.

Any inputs in this regard is greatly appreciated.


Hi, Runvar.

I think all of your questions are answered by the “Minimal wiring diagram for connecting a microcontroller to a DRV8824/DRV8825 stepper motor driver carrier (full-step mode)” located on the DRV8824 product page. If you still find something confusing after looking at the diagram and rest of the product page, please let me know.


Thanks Derrill. I think i have figured out most of the connections.
With regard to the Capacitor that need to be used a 100uf capacitor with what Voltage is recommended.
Is a 50 V 100uf capacitor fine?

Yes, a 50V 100uf capacitor is fine.
