Voltage for Pololu DRV8825

Post by BluePenguinGuitars » Thu Feb 25, 2021 6:17 am

In the wiki the voltage for the motor controllers listed as 12-36v. The DRV8825 controller can handle 48v is this a limitation of the 2.60 board? Can 48v be run through it safely?

Thanks!

We tested the V2.60 at 36v. For compatibility we labeled it at 36V for other pololu stepper drivers that don't go that high.

The board should technically be able to do it... The Caps on each stepper socket is rated for 50V but in my opinion the extra 2V is cutting it close.

Thank you, makes sense now that you explain it.
