Questions
How big is the Gnss module PCB?
It measures 89.1 × 92.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Gnss module use?
21 parts, built around the LM1117MP-ADJ, ESD9B5.0ST5G, MMZ1005B800CTD25 and NUP2105L. 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 module KiCad files?
From the spacelab-ufsc/gnss-module repository on GitHub, at the commit this page was made from: the board is hardware/gnss-module/gnss-module.kicad_pcb and its schematic hardware/gnss-module/gnss-module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gnss module design in my own project?
Its repository states no licence, so its author keeps all rights: ask spacelab-ufsc before reusing the design.
