Questions
How big is the PicoSense PCB?
It measures 29 × 41 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PicoSense use?
42 parts, built around the RP2040, W25X40CLSSIG, ICM-42688-P and ABM8-272-T3. 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 PicoSense KiCad files?
From the MrGeoTech/PicoSense repository on GitHub, at the commit this page was made from: the board is pcb/PicoSense/PicoSense.kicad_pcb and its schematic pcb/PicoSense/PicoSense.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PicoSense 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).

This was supposed to be a pyramid (or more of a triagle) but I thought I'd be too difficult to arrange the pixels in a neat way. So I made it a square. The name stuck.
