Questions
How big is the Lyra engine instrumentation board PCB?
It measures 90 × 80 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Lyra engine instrumentation board use?
121 parts, built around the TLV9001IDCK, TEENSY 4.1, TLV70933PKR and TPS54302. 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 Lyra engine instrumentation board KiCad files?
From the cuspaceflight/Lyra repository on GitHub, at the commit this page was made from: the board is lyra_engine_instrumentation_board.kicad_pcb and its schematic ignition.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lyra engine instrumentation board design in my own project?
Its repository states no licence, so its author keeps all rights: ask cuspaceflight before reusing the design.
