Questions
How big is the Rocket ejection PCB?
It measures 20.3 × 47.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Rocket ejection use?
52 parts, built around the ATMEGA328P-AU, BMP280, LIS331HH and LSM303D. 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 Rocket ejection KiCad files?
From the jonnydyer/rocket_ejection repository on GitHub, at the commit this page was made from: the board is rocket_ejection.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rocket ejection design in my own project?
Its repository states no licence, so its author keeps all rights: ask jonnydyer before reusing the design.
