Från klassrummen till rymden, en röd tråd från nyfikenhet till framtidens ingenjörer!
BOREALIS är ett projekt för högstadieelever som syftar till att introducera unga till teknik och rymdforskning genom praktiska, rymdnära experiment anpassade till deras kunskapsnivå. Genom att designa och bygga små experiment som skickas upp med stratosfäriska ballonger får eleverna uppleva ett verkligt rymdprojekt, vilket ger dem en första inblick i rymdteknik och ingenjörskonst. Projektet är utformat för att passa den grundläggande förståelse för naturvetenskap som elever på högstadiet har, och fungerar som en inspirerande introduktion till STEM-ämnen och framtida rymdrelaterade projekt.

Questions
How big is the Borealis PCB?
It measures 59.5 × 80.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Borealis use?
30 parts, built around the MSD-1-A, MCU08050C3300FP500, ASMT-YTD2-0BB02 and BAT-HLD-011-THM. 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 Borealis KiCad files?
From the ZER0-cmd/BOREALIS-1 repository on GitHub, at the commit this page was made from: the board is PCB/mainboard/Borealis.kicad_pcb and its schematic PCB/BOREALIS_MOTHERBOARD/BOREALIS_MOTHERBOARD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Borealis design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
