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!

Mykeyboard: common questions
What microcontroller does the Mykeyboard use?
The Mykeyboard is built around the ATMEGA32U4-AU, from the AVR/Arduino family.
How big is the Mykeyboard PCB?
The Mykeyboard measures 409 × 137 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Mykeyboard?
178 components, from 92 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Mykeyboard design files?
From the Skycode22/HIDs repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Mykeyboard design in my own project?
The repository has no license, so all rights stay with Skycode22. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Mykeyboard without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
