Questions
How big is the IntroBoard PCB?
It measures 81.5 × 34.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the IntroBoard use?
58 parts, built around the STM32G441KBT6, BMP390, BMI323 and MIC5501-3.0YM5-TR. 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 IntroBoard KiCad files?
From the SunDevilRocketry/IntroBoard2025 repository on GitHub, at the commit this page was made from: the board is IntroBoard/IntroBoard.kicad_pcb and its schematic IntroBoard/IntroBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the IntroBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask SunDevilRocketry before reusing the design.
