For a project in learning how circuits board work, how to solder, designing circuits and building them I would like to build my own mouse straight from scratch.

It would just be a simple mouse with a left and right click, and scroll wheel. Once I design the circuit board, I'm planning on 3D printing the casing for it and buying rep
