Questions
How big is the Hyperram sm x1 PCB?
It measures 20.5 × 43 mm and has 4 copper layers, 1.57 mm thick.
What parts does the Hyperram sm x1 use?
14 parts, built around the W957A8MFYA5I. 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 Hyperram sm x1 KiCad files?
From the picolemon/hyperram repository on GitHub, at the commit this page was made from: the board is pcb/hyperram-sm-x1.kicad_pcb and its schematic pcb/hyperram-sm-x1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hyperram sm x1 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).
