README
README.mdA custom PCB for the 2026 Hungarian CanSat competition
This is the the design me and my team are working on this year. This is the second year that we try ourselves at this competition. Dispite last years sub-optimal results we are determined to give our everything. Our goal this year is to get to the finals and launch our CanSat.

Questions
How big is the Cansat v3 PCB?
It measures 55.6 × 104.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Cansat v3 use?
90 parts, built around the MCP73871EV, AS7331-AQFM, BME680 and SCD40-D-R2. 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 Cansat v3 KiCad files?
From the NBER08/CanSat-PCB repository on GitHub, at the commit this page was made from: the board is cansat-v3.kicad_pcb and its schematic cansat-v3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cansat v3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask NBER08 before reusing the design.
