Questions
How big is the Resonance PCB?
It measures 104.3 × 34.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Resonance use?
123 parts, built around the CS43198-CNZ, TPS63070RNMR, TPS7A2018PDBV and TPS7A2033PDBV. 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 Resonance KiCad files?
From the SethTheDev/Resonance repository on GitHub, at the commit this page was made from: the board is Resonance.kicad_pcb and its schematic Resonance.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Resonance design in my own project?
Its repository states no licence, so its author keeps all rights: ask SethTheDev before reusing the design.
