Questions
How big is the Latte PCB?
It measures 50 × 50 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Latte use?
79 parts, built around the RP2040, W25Q16JVSNIQ, USBLC6-2SC6 and FSUSB30UMX. 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 Latte KiCad files?
From the WojtaCZ/latte-hw repository on GitHub, at the commit this page was made from: the board is latte.kicad_pcb and its schematic latte.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Latte 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).
