Thanks
Aisler was nice enough to make a last-minute run for 37c3 possible, and additionally sponsored a hundred PCBs to give out at the conference. Thanks a lot!

Questions
How big is the Tamarin c PCB?
It measures 37.8 × 52.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tamarin c use?
42 parts, built around the FUSB302BMPX and 74AVCH1T45W6. 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 Tamarin c KiCad files?
From the stacksmashing/tamarin-c-hw repository on GitHub, at the commit this page was made from: the board is tamarin-c.kicad_pcb and its schematic tamarin-c.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tamarin c design in my own project?
Its repository states no licence, so its author keeps all rights: ask stacksmashing before reusing the design.
