Questions

How big is the Hydrophone preamp PCB?

It measures 22 × 37.2 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Hydrophone preamp use?

34 parts, built around the OPA1642AID. 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 preamp KiCad files?

From the starlingcode/piezo-preamp repository on GitHub, at the commit this page was made from: the board is hydrophone_preamp.kicad_pcb and its schematic hydrophone_preamp.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Hydrophone preamp design in my own project?

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