Questions
How big is the ErgoV PCB?
It measures 133.4 × 86.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ErgoV use?
65 parts, built around the MDBT50Q-1MV2, USBLC6-2SC6, AO3401A and MBR0540. 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 ErgoV KiCad files?
From the vibsthebot/ergoV repository on GitHub, at the commit this page was made from: the board is src/left/ergoV.kicad_pcb and its schematic src/left/ergoV.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ErgoV design in my own project?
Its repository states no licence, so its author keeps all rights: ask vibsthebot before reusing the design.
