Board Revisions
| Revision | Notes |
|---|---|
| V0 | Initial version |
Note #1: All of the functionality hasn't been tested yet, only configuration from MMOD and blinky on an LED PMOD.
Note #2: There should probably be a 10K pull-up on RAM_SS, but configuration appears to work without it.
Note #3: Kapton tape is recommended under front of the USB-B connector.

Questions
How big is the Mde PCB?
It measures 70 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mde use?
77 parts, built around the ICE40UP5K-SG48ITR50 and AMS1117-3.3. 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 Mde KiCad files?
From the machdyne/endlos repository on GitHub, at the commit this page was made from: the board is pcb/mde.kicad_pcb and its schematic pcb/mde.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mde design in my own project?
Its repository states no licence, so its author keeps all rights: ask machdyne before reusing the design.
