Questions
How big is the Zmod PCB?
It measures 50 × 70 mm and has 4 copper layers, 1.55 mm thick.
What parts does the Zmod use?
27 parts, built around the SN74LVC1T45DBV, ECS-2520MVQ-1000-BN-TR and MDT420M02001. 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 Zmod KiCad files?
From the hdlguy/kicad repository on GitHub, at the commit this page was made from: the board is zmod_m2_ssd/zmod.kicad_pcb and its schematic alinx_carrier/alinx_carrier.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Zmod design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
