Questions

How big is the VRefBoard PCB?

It measures 74 × 41 mm and has 2 copper layers, 1.6 mm thick.

What parts does the VRefBoard use?

10 parts. 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 VRefBoard KiCad files?

From the Enerwize/PowerFlies repository on GitHub, at the commit this page was made from: the board is Hardware/VRefBoard/VRefBoard.kicad_pcb and its schematic Hardware/VRefBoard/VRefBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the VRefBoard design in my own project?

Its repository states no licence, so its author keeps all rights: ask Enerwize before reusing the design.
