Questions
How big is the FPGC4IOboard PCB?
It measures 95.3 × 126.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FPGC4IOboard use?
108 parts, built around the CH376T, FT232RL and BSS138. 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 FPGC4IOboard KiCad files?
From the RPG-7/FPGC4 repository on GitHub, at the commit this page was made from: the board is PCB/FPGC4IOboard/FPGC4IOboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the FPGC4IOboard 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).
