A PCB designed to make Klipper's input shaping much easier by simplifying the wiring and config for measuring resonances. You just need this PCB and a USB C cable.

- KUSBA v2 Instructions - Rampon Firmware
- KUSBA v2 Instructions - Klipper Firmware
- KUSBA v1 Instructions
Rampon Firmware is recommended. It is easier to flash and less buggy than Klipper on RP2040.
Toolhead mounts can be found here.
The CAD model of the PCB and some toolhead mounts can be found here.
