Questions
How big is the Microom PCB?
It measures 56.4 × 62.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Microom use?
139 parts, built around the BLM15AG102SN1 and PCM1865DB. 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 Microom KiCad files?
From the Kreyl/Microom repository on GitHub, at the commit this page was made from: the board is Microom_hw/Microom.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Microom design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kreyl before reusing the design.
