Revolt A1

Revolt is a dual 48 V compatible stepper motor driver add-on board. It is based on TMC5160.

Klipper config

This config is using stepper x and y as the high voltage drivers, typical of a core-xy printer setup for speed. This gives the option of having 4 Z-drives and two extruders, 8 steppers in total.
