Questions
How big is the Flight computer PCB?
It measures 30 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Flight computer use?
38 parts, built around the ATMEGA328PB-AU, BMP388, BMI088 and MIC5504-3.3YM5. 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 Flight computer KiCad files?
From the wFairmanOlin/OlinRocketryClub repository on GitHub, at the commit this page was made from: the board is peregrine/flight_computer/flight_computer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Flight computer design in my own project?
Its repository states no licence, so its author keeps all rights: ask wFairmanOlin before reusing the design.
