Questions
How big is the USB VSense gamma PCB?
It measures 140.2 × 47.5 mm and has 4 copper layers, 0.78 mm thick.
What parts does the USB VSense gamma use?
87 parts, built around the ATTINY406-MN 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 USB VSense gamma KiCad files?
From the Meticulous-Technologies/USB_VSense repository on GitHub, at the commit this page was made from: the board is hardware/KiCAD/USB_VSense_gamma/USB_VSense_gamma.kicad_pcb and its schematic hardware/KiCAD/USB_VSense_gamma/USB_VSense_gamma.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the USB VSense gamma design in my own project?
Its repository states no licence, so its author keeps all rights: ask Meticulous-Technologies before reusing the design.
