Questions
How big is the Krish Flight Computer PCB?
It measures 47.1 × 65.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Krish Flight Computer use?
33 parts, built around the MS5611-01BA03 and BMI088. 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 Krish Flight Computer KiCad files?
From the klzsh/L1-Rocket repository on GitHub, at the commit this page was made from: the board is PCB/Krish_Flight_Computer.kicad_pcb and its schematic PCB/Krish_Flight_Computer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Krish Flight Computer design in my own project?
Its repository states no licence, so its author keeps all rights: ask klzsh before reusing the design.
