Questions
How big is the Stima V4 Master PCB?
It measures 126.8 × 99.9 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Stima V4 Master use?
177 parts, built around the STM32L496VGT6, TJA1443ATK/0Z, AT25SF641B-SHB-B and MAX20077ATCA/VY+. 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 Stima V4 Master KiCad files?
From the r-map/rmap repository on GitHub, at the commit this page was made from: the board is kicad/stima_v4/Stima V4 Master Rev1_1_24/Stima V4 Master.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stima V4 Master design in my own project?
Its repository states no licence, so its author keeps all rights: ask r-map before reusing the design.
