Parts list
- Logitech M575 mouse
- 1 AA battery holder
- 5 m2.5x8mm screws
- Double sided nano tape
- Soldering equipment
Instructions
- Print the thumb cluster model and replace the stock thumb cluster with it.
- Print the wedge model, and secure it to the bottom of the keyboard half with 3 screws.
- Turn on the Logitech M575 and connect it to your PC using either Bluetooth or the Logitech dongle.
- Open the Logitech M575 and remove the main PCB, the longest of the two flat cables, and the trackball mount.
- Desolder the battery holder from the PCB and solder the AA battery holder from the parts list in its place.
- Tape the battery holder to the bottom of the thumb cluster.
- Turn the switch on the main PCB to “On”, and stick it in the cutout using the nano tape.
- Attach the trackball mount to the bottom of the thumb cluster using two m2.5 screws (drilling two holes). To correctly align the ball you may need to add some spacers to one of the two screws.
- Once aligned connect the trackball PCB to the main PCB looping the flat cable through the cutout in the wedge.
- Your trackball should now be functional.
