Questions
How big is the Md rev-1 PCB?
It measures 20 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Md rev-1 use?
24 parts, built around the 3352T-1-201LF and 500SSP1S1M6QEA. 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 Md rev-1 KiCad files?
From the khray/meditation-device repository on GitHub, at the commit this page was made from: the board is Md-rev-1.kicad_pcb and its schematic Md-rev-1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Md rev-1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask khray before reusing the design.
