Questions
How big is the Floe PCB?
It measures 130.5 × 50.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Floe use?
174 parts, built around the PE4259-63, 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 Floe KiCad files?
From the Kreyl/Floe repository on GitHub, at the commit this page was made from: the board is Floe_hw/Floe.kicad_pcb and its schematic Floe_hw/Floe.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Floe design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kreyl before reusing the design.
