Ilulissat is a wireless environment sensor board, intended to run as low power as possible.
It consists of:
The wireless chip supports both Bluetooth, Zigbee and OpenThread.
The first revision of the software will be written for Bluetooth Low energy using a standard profile, e.g Temperature and Humidity, hopefully allowing it to use some standard app off playstore/apple appstore.

Questions
What parts does the Ilulissat use?
31 parts, built around the CR2032. 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 Ilulissat KiCad files?
From the EnJens/ilulissat repository on GitHub, at the commit this page was made from: the board is ilulissat.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ilulissat design in my own project?
Its repository states no licence, so its author keeps all rights: ask EnJens before reusing the design.
