Questions
How big is the Nrf52-sensor tag PCB?
It measures 36 × 33 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Nrf52-sensor tag use?
23 parts, built around the MS88SF2, LTR-308ALS-01, MS860702BA01-50 and APHF1608LSEEQBDZGKC. 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 Nrf52-sensor tag KiCad files?
From the HomeSmartMesh/nrf52_thread_sensortag repository on GitHub, at the commit this page was made from: the board is nrf52-sensor-tag.kicad_pcb and its schematic nrf52-sensor-tag.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nrf52-sensor tag 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).
