Questions
How big is the AQUA PCB V2 PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.61 mm thick.
What parts does the AQUA PCB V2 use?
105 parts, built around the FE1.1S, RT9742GGJ5, AMS1117-3.3 and AP22652W6. 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 AQUA PCB V2 KiCad files?
From the samnadol/whirlpool_rov repository on GitHub, at the commit this page was made from: the board is v2/AQUA_PCB_V2.kicad_pcb and its schematic v1/AQUA_CM4.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AQUA PCB V2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask samnadol before reusing the design.
