Questions
How big is the HydraBreakout PCB?
It measures 60 × 37 mm and has 4 copper layers, 1.6 mm thick.
What parts does the HydraBreakout use?
63 parts, built around the RP2040, FT231XQ-R, 24FC04T-E/OT36KVAO and AP2112K-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 HydraBreakout KiCad files?
From the cnf/HydraBreakout repository on GitHub, at the commit this page was made from: the board is HydraBreakout.kicad_pcb and its schematic CoMCU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HydraBreakout design in my own project?
Its repository states no licence, so its author keeps all rights: ask cnf before reusing the design.
