Questions
How big is the EiMOSNanoShield PCB?
It measures 93 × 81.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EiMOSNanoShield use?
44 parts, built around the CD74HC4067M, RJ45 and BSS138. 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 EiMOSNanoShield KiCad files?
From the ChitoKim/EiMOS_PCB repository on GitHub, at the commit this page was made from: the board is EiMOSNanoShield.kicad_pcb and its schematic EiMOSNanoShield.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EiMOSNanoShield design in my own project?
Its repository states no licence, so its author keeps all rights: ask ChitoKim before reusing the design.
