Questions
How big is the Strelka Flight Computer PCB?
It measures 91 × 30.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Strelka Flight Computer use?
170 parts, built around the MAX-M10S-00B, LM321, MS561101BA03-50 and AMS1117-3.3. 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 Strelka Flight Computer KiCad files?
From the LulaUAV/Strelka-Flight-Computer repository on GitHub, at the commit this page was made from: the board is Design Files/Strelka_Flight_Computer/Strelka_Flight_Computer.kicad_pcb and its schematic Design Files/Strelka_Flight_Computer/915MHz_Radio.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Strelka Flight Computer design in my own project?
Its repository states no licence, so its author keeps all rights: ask LulaUAV before reusing the design.
