Questions
How big is the Sfp adapter PCB?
It measures 60 × 22.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sfp adapter use?
10 parts, built around the HC-SFP-01L. 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 Sfp adapter KiCad files?
From the bigbigmdm/SFP-Master-Hardware repository on GitHub, at the commit this page was made from: the board is kicad-adapter/sfp_adapter.kicad_pcb and its schematic KiCad/sfp_adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sfp adapter 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).
