Questions
How big is the Flute PCB?
It measures 310.5 × 21.4 mm and has 4 copper layers, 1.5 mm thick.
What parts does the Flute use?
104 parts, built around the CC1101RGP, CS42L52-CNZ, BLM15AG102SN1 and IRLML6401. 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 Kreyl/Flute repository on GitHub, at the commit this page was made from: the board is Flute_hw/Flute.kicad_pcb and its schematic Flute_hw/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 states no licence, so its author keeps all rights: ask Kreyl before reusing the design.
