Model Change Notices
We use Model Change Notices (MCNs) to track rework made in between CAD updates andboard spins. These are preserved in this repo for historical and reference reasons even after the CAD has been updated.
Status
The CAD represents what was built without the MCN(s) applied.

Questions
How big is the Spimux PCB?
It measures 75 × 20 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Spimux use?
23 parts, built around the ADG3308BRUZ, LM1117-1.8 and TS3A27518EPW. 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 Spimux KiCad files?
From the oxidecomputer/hw-spimux repository on GitHub, at the commit this page was made from: the board is spimux.kicad_pcb and its schematic spimux.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Spimux design in my own project?
Its repository publishes it under the MPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
