Questions
How big is the Underwater PCB?
It measures 93.3 × 97.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Underwater use?
73 parts, built around the ESP32-WROOM-32, TPS62133RGT, FT230XS-U and ICM-20948. 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 Underwater KiCad files?
From the lets-make-something/underwater-drone repository on GitHub, at the commit this page was made from: the board is kicad/underwater.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Underwater design in my own project?
Its repository states no licence, so its author keeps all rights: ask lets-make-something before reusing the design.
