Questions
How big is the Flute PCB?
It measures 230 × 20 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Flute use?
47 parts, built around the RP2040 and W25Q128JVSIQ. 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 Flute KiCad files?
From the KN-Hardwire/Electronic-Flute repository on GitHub, at the commit this page was made from: the board is hardware/flute.kicad_pcb and its schematic hardware/flute.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Flute design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
