KUSBA is a PCB designed to make Klipper's input shaping much easier by simplifying the wiring and config for measuring resonances. It is an MCU and the ADXL345 accelerometer on one PCB. You just need this PCB and a USB C cable, no complicated and unreliable SPI wires! Compatible with every 3D printer running Klipper and has a free USB port. Comes with (Rampon Anchor) firmware pre-flashed so you can just edit your Klipper config, connect the KUSBA and start measuring resonances.
