Questions
How big is the V2 PCB?
It measures 430 × 118.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the V2 use?
265 parts, built around the E73-2G4M08S1C, MC-121-L124, S2B-PH-K-S(LF)(SN) and 1N4148W. 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 V2 KiCad files?
From the Jaydosu/V2 repository on GitHub, at the commit this page was made from: the board is V2.3.kicad_pcb and its schematic MCU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the V2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Jaydosu before reusing the design.
