Questions
How big is the BirdAudio PCB?
It measures 34.5 × 28 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BirdAudio use?
11 parts, built around the GMC10X7R104K25NT, RMCF0603FT100K, B2B-PH-K-S and ICS-43434. 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 BirdAudio KiCad files?
From the twhalm/birdnet-pcb repository on GitHub, at the commit this page was made from: the board is BirdAudio.kicad_pcb and its schematic BirdAudio.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BirdAudio design in my own project?
Its repository states no licence, so its author keeps all rights: ask twhalm before reusing the design.
