Questions
How big is the GNSS Firehose PCB?
It measures 117.9 × 99.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the GNSS Firehose use?
519 parts, built around the MAX2112CTI+, MGA-68563, KSZ9031RNXCA and MAX19505ETM+. 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 GNSS Firehose KiCad files?
From the pmonta/GNSS_Firehose repository on GitHub, at the commit this page was made from: the board is kicad/GNSS_Firehose.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the GNSS Firehose design in my own project?
Its repository states no licence, so its author keeps all rights: ask pmonta before reusing the design.
