Questions
How big is the Flight Computer Lite PCB?
It measures 66.8 × 25.4 mm and has 4 copper layers, 4.69 mm thick.
What parts does the Flight Computer Lite use?
61 parts, built around the STM32G4A1KEU6, BMP390, SST25VF040B-50-4I-S2AE-T and 2N7002W-7-F-ES. 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 Lite KiCad files?
From the cacost12/SDR-Flight-Computer-Lite-PCB repository on GitHub, at the commit this page was made from: the board is src/Flight-Computer-Lite/Flight-Computer-Lite.kicad_pcb and its schematic src/Flight-Computer-Lite/Flight-Computer-Lite.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Flight Computer Lite design in my own project?
Its repository states no licence, so its author keeps all rights: ask cacost12 before reusing the design.
