Questions
How big is the AuraPlug PCB?
It measures 40 × 15 mm and has 4 copper layers, 1.6 mm thick.
What parts does the AuraPlug use?
101 parts, built around the PCM5102APW, 2450AT18B100 and PRTR5V0U2X. 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 AuraPlug KiCad files?
From the LyndLabs/AuraPlug repository on GitHub, at the commit this page was made from: the board is AuraPlug/AuraPlug.kicad_pcb and its schematic AuraPlug/AuraPlug.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AuraPlug design in my own project?
Its repository states no licence, so its author keeps all rights: ask LyndLabs before reusing the design.
