The older, unrelated V2.2 (S-A-A-2) design is open (github.com/nanovna-v2/NanoVNA2, gEDA schematics + Gerbers + BOM under CC-BY-NC-SA) but is a different, earlier hardware revision, not the Plus4 Pro sold today, so it is intentionally NOT listed as a repo for this entry. Parts listed are third-party teardown reports (Kerry Wong / Electro707 blogs, NanoRFE forum) for the V2 Plus4 family generally, not vendor-confirmed for the exact 'Pro' SKU - treat as indicative only.",
