Progress on a fully custom mouse.
Over the past few years I've slowly been gaining knowledge about electronics, and recently I've been thinking there's not really anything about mouse technology that really mystifies me, so why not try to design and build one myself? It might be a little overambitious, but there's nothing wrong with failing.
Details of the current design:
PMW3360 (3389 should be an easy change though)
8 hardware debounced switches, 3 of which will be on separate board, for thumb buttons.
MCU: EFM8UB10F16G-C-QFN28 (may change later, but want to at least try it first)
61mm x 60mm, but I think I can get it smaller.
Prototype shell will be made by vacuforming over a clay sculpture. If that doesn't work out I may try shapeways.
This is the first PCB I've laid out, and I'm not quite done with it yet, but I think it's good enough to get some feedback on. Learning to use KiCAD at the same time:
