Questions
How big is the CM4-NAS PCB?
It measures 88.5 × 72.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the CM4-NAS use?
30 parts, built around the 74LVC1G07SE-7-MS and EMC2301-1-ACZL-TR. 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 CM4-NAS KiCad files?
From the johnaa123/CM4-NAS repository on GitHub, at the commit this page was made from: the board is CM4_NAS.kicad_pcb and its schematic CM4_NAS.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CM4-NAS design in my own project?
Its repository states no licence, so its author keeps all rights: ask johnaa123 before reusing the design.
