🖱️ DIY Custom Gaming Mouse (Blueprint Project)

A fully custom-built gaming mouse designed from scratch — including PCB, firmware, and 3D-printable body. This project is part of my Hack Club Blueprint submission, where I explore hardware design, embedded programming, and product customization.

Features Custom-designed PCB for mouse electronics Firmware written in C for full control 3D printable STL files for complete mouse body Supports high-performance optical sensor Multiple buttons with customizable inputs Fully customizable design (case + PCB)

Hardware Custom PCB (designed in KiCad) Optical sensor (e.g. PMW3360 or similar) Microcontroller (depends on your design) Mouse switches (left, right, side buttons) Scroll wheel encoder USB connection

The firmware is written in C and handles:

Sensor tracking Button inputs USB communication with PC Custom key bindings

Questions

How big is the Mouse pcb PCB?

It measures 49.8 × 61.7 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Mouse pcb use?

71 parts, built around the RP2040, PMW3360DM-T2QU, W25Q32JVSSIQ and ABM8-272-T3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Mouse pcb KiCad files?

From the slothfs/mouse_air repository on GitHub, at the commit this page was made from: the board is mouse_pcb.kicad_pcb and its schematic mouse_semantic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Mouse pcb design in my own project?

Its repository states no licence, so its author keeps all rights: ask slothfs before reusing the design.
