Questions
How big is the Main PCB PCB?
It measures 178.5 × 70 mm and has 4 copper layers, 4.69 mm thick.
What parts does the Main PCB use?
79 parts, built around the LTR-329ALS-01, 24LC64-I/SNG, RFM95W-868S2 and USBLC6-2SC6. 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 Main PCB KiCad files?
From the vives-projectwerk-2021/Microcontroller_pcb repository on GitHub, at the commit this page was made from: the board is Main_PCB.kicad_pcb and its schematic Main_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Main PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask vives-projectwerk-2021 before reusing the design.
