Questions
How big is the Submission PCB?
It measures 198.4 × 84.1 mm and has 2 copper layers, 1.2 mm thick.
What parts does the Submission use?
109 parts, built around the STM32F072CBT6 and PRTR5V0U2X. 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 Submission KiCad files?
From the mhzkb/submission repository on GitHub, at the commit this page was made from: the board is pcb/submission.kicad_pcb and its schematic pcb/submission.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Submission design in my own project?
Its repository states no licence, so its author keeps all rights: ask mhzkb before reusing the design.
