Questions
How big is the Avbay PCB?
It measures 30.5 × 83.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Avbay use?
64 parts, built around the LT1376IS8-5#PBF, MIC5209-3.3YS, BSS138DW and DMN2041LSD. 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 Avbay KiCad files?
From the drahosj/avionics repository on GitHub, at the commit this page was made from: the board is Hardware/avbay.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Avbay design in my own project?
Its repository states no licence, so its author keeps all rights: ask drahosj before reusing the design.
