Questions

How big is the Computer upgraded mouse v2 PCB?

It measures 100.1 × 84.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Computer upgraded mouse v2 use?

97 parts, built around the MP2338GTL-Z, AMS1117-3.3, SFH 4545 and TEFT4300. 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 Computer upgraded mouse v2 KiCad files?

From the NeverNotJohn/Fresno-State-Micro-Mouse repository on GitHub, at the commit this page was made from: the board is v2/hardware/computer_upgraded_mouse_v2/computer_upgraded_mouse_v2.kicad_pcb and its schematic v1.5/hardware/kit/mainboard/computer_upgraded_mouse_v1_5.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Computer upgraded mouse v2 design in my own project?

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