Questions
What parts does the OpenAquatix Hardware use?
351 parts, built around the TPD4E05U06DQAR, TS5A4624DCK, TLV75733PDRV and TPS22919DCK. 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 OpenAquatix Hardware KiCad files?
From the ericvoi/OpenAquatix-Hardware repository on GitHub, at the commit this page was made from: the board is v2/src/OpenAquatix-Hardware.kicad_pcb and its schematic v1/src/Connections.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the OpenAquatix Hardware design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
