Questions
How big is the Main H743VI PCB?
It measures 150 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Main H743VI use?
75 parts, built around the LM2676S-5.0, BME280, AMS1117-3.3 and SS36. 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 H743VI KiCad files?
From the motion55/Main_H743VI repository on GitHub, at the commit this page was made from: the board is Main_H743VI.kicad_pcb and its schematic Main_H743VI.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Main H743VI design in my own project?
Its repository states no licence, so its author keeps all rights: ask motion55 before reusing the design.
