README
README.mdVerakey
A custom Yubikey I'm designing to act as a cool keychain for my backpack! Along with having a keyring for me to mount it to a carabiner, it doesn't have a button, but instead a OLED screen I plan on adding some cute animations to, maybe a frog or something.
It uses the STM32L432KBUx with an ATECC608 for maximum security, and will have the following protocol stack -FIDO2 -U2F -HOTP -PIV
for maximal security. I also added a cool silkscreen.

Questions
How big is the Verakey PCB?
It measures 59 × 20 mm and has 2 copper layers, 0.8 mm thick.
What parts does the Verakey use?
26 parts, built around the ATECC608A-MAHDA-S, TLV75533PDBV, USBLC6-2SC6 and SK6812MINI-E. 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 Verakey KiCad files?
From the Veracles-Hackclub/Verakey repository on GitHub, at the commit this page was made from: the board is Verakey.kicad_pcb and its schematic Verakey.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Verakey design in my own project?
Its repository states no licence, so its author keeps all rights: ask Veracles-Hackclub before reusing the design.
