Questions
How big is the 32kb PCB?
It measures 252.9 × 110.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 32kb use?
124 parts, built around the RP2040, W25Q16JVUXIQ, 1N4148W and 0805L050WR. 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 32kb KiCad files?
From the doesntfazer/frigate repository on GitHub, at the commit this page was made from: the board is Frigate V1 integrated/Frigate Kicad/32kb.kicad_pcb and its schematic Frigate V1 integrated/Frigate Kicad/32kb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 32kb 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).
