Questions

How big is the CF reader JM PCB?

It measures 62.8 × 93 mm and has 4 copper layers, 1.6 mm thick.

What parts does the CF reader JM use?

64 parts, built around the TLV62569DBV, N7E50-A516PK-30 and BLM15KD200SN1D11. 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 CF reader JM KiCad files?

From the will127534/Microdrive-CF-Card-Reader repository on GitHub, at the commit this page was made from: the board is JM20337_PCB/CF_reader_JM.kicad_pcb and its schematic GL834_PCB/CF_reader_GL.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the CF reader JM 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).
