Questions
How big is the SmartTagPrototype PCB?
It measures 59.5 × 43.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SmartTagPrototype use?
50 parts, built around the NRF52810-QFAA-R7 and AEM30940-QFN. 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 SmartTagPrototype KiCad files?
From the SKN-vFly/SmartTagPrototype repository on GitHub, at the commit this page was made from: the board is SmartTagPrototype.kicad_pcb and its schematic SmartTagPrototype.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SmartTagPrototype design in my own project?
Its repository states no licence, so its author keeps all rights: ask SKN-vFly before reusing the design.
