The Refractor Bypass PCB was designed to simplify the wiring of the Refractor Overdrive project, but it will work for any Klon Centaur clone that uses the three off-board resistors. At only 0.8” wide by 0.75” tall, it’s only barely larger than a 3PDT stomp switch. Save yourself the hassle of wiring those resistors to the switch lugs!
The pads match up directly with the Aion Refractor PCB project, so you can run the wires straight across and be done with it. Check the documentation for a description of each of the connections if you want to use this with a different Centaur PCB.
