Questions
How big is the SG10 FT232H PCB?
It measures 40 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SG10 FT232H use?
16 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 SG10 FT232H KiCad files?
From the quantrng/quantrng.github.io repository on GitHub, at the commit this page was made from: the board is hardware/kicad/SG10_FT232H/SG10_FT232H.kicad_pcb and its schematic hardware/kicad/SG10_FT232H/SG10_FT232H.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SG10 FT232H design in my own project?
Its repository states no licence, so its author keeps all rights: ask quantrng before reusing the design.
