Questions

How big is the Hydrophone PCB?

It measures 26 × 75 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Hydrophone use?

115 parts, built around the PCM2912APJTR and MMBFJ201. 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 Hydrophone KiCad files?

From the Remus287/Hydrophone repository on GitHub, at the commit this page was made from: the board is Hydrophone.kicad_pcb and its schematic 9V_To_3.5mm_Jack.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Hydrophone design in my own project?

Its repository states no licence, so its author keeps all rights: ask Remus287 before reusing the design.
