Questions
How big is the FuncGen PCB?
It measures 67 × 42 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FuncGen use?
72 parts, built around the RP2040, IA0515D, W25Q32JVSSIQ and LM1117-3.3. 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 FuncGen KiCad files?
From the velechit/HomeLAB repository on GitHub, at the commit this page was made from: the board is board/FuncGen/FuncGen.kicad_pcb and its schematic board/FuncGen/FuncGen.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FuncGen 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).
