Questions
How big is the Venturi MainPCB PCB?
It measures 166.1 × 91.4 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Venturi MainPCB use?
114 parts, built around the DRV8212PDSG, SK6812, BSS138 and BAT54C. 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 Venturi MainPCB KiCad files?
From the David207025/Venturi repository on GitHub, at the commit this page was made from: the board is Hardware/Venturi_MainPCB/Venturi_MainPCB.kicad_pcb and its schematic Hardware/Venturi_MainPCB/Venturi_MainPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Venturi MainPCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask David207025 before reusing the design.
