Questions
How big is the Function gen PCB?
It measures 71 × 60.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Function gen use?
90 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 Function gen KiCad files?
From the sirlilpanda/function-generator repository on GitHub, at the commit this page was made from: the board is hardware/function_gen.kicad_pcb and its schematic hardware/function_amplifier.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Function gen design in my own project?
Its repository states no licence, so its author keeps all rights: ask sirlilpanda before reusing the design.
