Questions
How big is the SigmaLink USBi PCB?
It measures 64 × 39 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SigmaLink USBi use?
40 parts, built around the 24LC512-I/P, 74LVC2G66DP, LM1117-3.3 and MAX809S. 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 SigmaLink USBi KiCad files?
From the xfdr0805/usbi repository on GitHub, at the commit this page was made from: the board is SigmaLink-USBi.kicad_pcb and its schematic SigmaLink-USBi.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SigmaLink USBi design in my own project?
Its repository states no licence, so its author keeps all rights: ask xfdr0805 before reusing the design.
