Realy fast shipment procces. Some parts not on that card. You should remove that parts from old card. After that proccess everything work perfect. i changed switches to 50m click omron switches. You have to cut board pins little bit , i used dremel with dremels sand paper tool. İf you dont have this kind of tools for sanding. You can use nail clippers. After sand procces sample images added. You can check board pin sizes from attachmet photos.
warning doesnt come with scroll sensor had to desolder and resolder from previous board
