Questions
How big is the VLF5 PCB?
It measures 34 × 56 mm and has 6 copper layers, 1.6 mm thick.
What parts does the VLF5 use?
106 parts, built around the CAM-M8Q-0, E22-900MM22S, ISO1044BD and LIS2MDL. 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 VLF5 KiCad files?
From the McMaster-Rocketry-Team/VLF5 repository on GitHub, at the commit this page was made from: the board is pcb/VLF5.kicad_pcb and its schematic pcb/Peripherals.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the VLF5 design in my own project?
Its repository states no licence, so its author keeps all rights: ask McMaster-Rocketry-Team before reusing the design.
