Questions
How big is the PicoEVB PCB?
It measures 22.5 × 30 mm and has 4 copper layers, 0.8 mm thick.
What parts does the PicoEVB use?
107 parts, built around the FT230XQ-R, TPS82085SIL, MIC47050-1.2YML-TR and S25Q. 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 PicoEVB KiCad files?
From the RHSResearchLLC/PicoEVB repository on GitHub, at the commit this page was made from: the board is Hardware/board_design/PicoEVB.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PicoEVB design in my own project?
Its repository states no licence, so its author keeps all rights: ask RHSResearchLLC before reusing the design.
