Keychain shaped like Tux, the Linux mascot. But it's not just a keychain, it runs embedded Linux!
Unfortunately this is more expensive than usual due to tariffs and inflation. (Probably cheaper in other countries.)
This project is not made by the All Things Linux 501(c)(3) organization. This project is made by All Things Linux staff members.
NOTE: This is still in the prototype stage, changes to the design are likely.
- This is a 4-layer PCB so it can fit in the Tux keychain form factor.
- Make sure you use ENIG for the PCB finish, else Tux will be gray instead of gold. (If you want a gray Tux, seek help.)
- This is designed for JLCPCBs assembly service, some parts are LCSC exclusive*.
*You can probably find them on other chinese distributors, but I don't know which ones.
The Allwinner F1C100s footprint/symbol is from https://github.com/thirtythreeforty/3340_kicad (F1C100s symbol, QFN-88_EP_10x10_Pitch0.4mm footprint). Same for the JW5211 symbol and footprint.
Schematic heavily based on the business card design by thirtythreeforty (https://www.thirtythreeforty.net/posts/2019/12/my-business-card-runs-linux/businesscard.pdf).
