Questions
How big is the Lyrav3og PCB?
It measures 50 × 60 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Lyrav3og use?
135 parts, built around the RP2040, W25Q16JVUXIQ, LIS3MDL and MPL3115A2R1. 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 Lyrav3og KiCad files?
From the prs2026/Lyra-flight-computer repository on GitHub, at the commit this page was made from: the board is Hardware/kicad/Lyra_flight_computer/lyra V3/deprecated/Lyrav3og.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lyrav3og design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
