Questions
How big is the Owlets PCB?
It measures 10.2 × 114.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Owlets use?
39 parts, built around the NE5532 and OPA2134UA. 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 Owlets KiCad files?
From the apaleslimghost/synths repository on GitHub, at the commit this page was made from: the board is eurorack/modules/owlets/owlets.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Owlets design in my own project?
Its repository states no licence, so its author keeps all rights: ask apaleslimghost before reusing the design.
