Build Details

The PCB must be ordered (e.g. from jlcpcb) in 1.6mm thickness with surface finish ENIG at minimum.

You'll want to lay the Card slot adapter pcb center over top of the module making the module and pcb as flush together as possible and solder pin by pin the module to the pcb.

3D Printed Case Enclosure

You'll need to 3D print the case enclosure Top and Bottom pieces from the Case folder to use it in your Memcard Slot preferably on an FDM printer, the case screws are countersunk self tapping M2x5 screws.

Questions

How big is the BBAMemCardPCB PCB?

It measures 30 × 49.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the BBAMemCardPCB use?

3 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 BBAMemCardPCB KiCad files?

From the silverstee1/WizNet-Card-Slot-Adapter repository on GitHub, at the commit this page was made from: the board is Kicad/BBAMemCardPCB.kicad_pcb and its schematic Kicad/BBAMemCardPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the BBAMemCardPCB design in my own project?

Its repository publishes it under the Unlicense licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
