Questions
How big is the Vr module PCB?
It measures 20.3 × 22.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Vr module use?
44 parts, built around the MCP6004-E/P, NC7SB3157P6X, 74HC02 and MAX9142ESA+. 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 Vr module KiCad files?
From the mck1117/vr-interface repository on GitHub, at the commit this page was made from: the board is vr_module.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vr module design in my own project?
Its repository states no licence, so its author keeps all rights: ask mck1117 before reusing the design.
