Questions
How big is the Control board prototype PCB?
It measures 98 × 54.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Control board prototype use?
77 parts, built around the BU2505FV-E2, LM358 and LM317. 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 Control board prototype KiCad files?
From the Windfisch/analog-synth repository on GitHub, at the commit this page was made from: the board is hardware/control_board_prototype/control_board_prototype.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Control board prototype 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).
