Questions
How big is the MicroSD Express Sniffer PCB?
It measures 35.1 × 92.1 mm and has 2 copper layers, 0.8 mm thick.
What parts does the MicroSD Express Sniffer use?
6 parts. 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 MicroSD Express Sniffer KiCad files?
From the NVNTLabs/switch2-SDEX2M2 repository on GitHub, at the commit this page was made from: the board is MicroSD Express Sniffer V0.3/MicroSD Express Sniffer.kicad_pcb and its schematic M.2 NVMe SSD Breakout Board/SDEX2M2 M.2 NVMe SSD Breakout Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MicroSD Express Sniffer design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
