HID (Human Interface Device) projects; Keyboards, trackballs, controllers of all sorts.
This repo is for the HID projects I have been working on and are making public for anyone to use, replicate, innovate, and otherwise utilize to their liking. If you make any new design changes/innovations, I would love to see them and potentially add them to the repository!
Feel free to message me with any questions or if you have any suggestions to make things better overall!

Questions
How big is the Mcu daughterboard PCB?
It measures 32.2 × 193.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mcu daughterboard use?
18 parts, built around the ATMEGA32U4. 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 Mcu daughterboard KiCad files?
From the Skycode22/HIDs repository on GitHub, at the commit this page was made from: the board is Store Boards/My75 [Final]/My75 Rev2/pcb/mcu daughterboard/mcu daughterboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mcu daughterboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask Skycode22 before reusing the design.
