Questions
How big is the Flatbox rev4 PCB?
It measures 210 × 124.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Flatbox rev4 use?
49 parts, built around the RP2040, W25Q128JVSIQ and AMS1117-3.3. 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 Flatbox rev4 KiCad files?
From the cr1tbit/flatbox-v4 repository on GitHub, at the commit this page was made from: the board is Flatbox-rev4.kicad_pcb and its schematic Flatbox-rev4.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Flatbox rev4 design in my own project?
Its repository states no licence, so its author keeps all rights: ask cr1tbit before reusing the design.
