Questions
What parts does the WakeBand use?
33 parts, built around the NRF52840-QFAA-F-R7. 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 WakeBand KiCad files?
From the HydrogreenPollub/pcb-wake-band repository on GitHub, at the commit this page was made from: the board is WakeBand.kicad_pcb and its schematic WakeBand.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the WakeBand design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
