Gabriel Tenna White's version 2 hardware and firmware design efforts are well documented on this forum and on her GitHub pages. Hugen and edy555 reportedly have version 2 efforts in the work, but so far, nothing as concrete as Gabriel's design. Hugen has documented a 4-inch F303 branch, that admittedly is not a version 2 design.
I was just wondering if any forum members have come across credible resources where either Hugen's or edy555's version 2 designs could be followed. My own research has not turned up anything close to what Gabriel has released, but I have not delved into any foreign language resources.
Since edy555 originated the NanoVNA design, I'm surprised he is not at the forefront of the V2 design effort. Gabriel's V2 design appears to have leap-frogged both his and hugen's. Still, its early in the race and the anticipated 2020 releases of the NanoVNA V2 show great promise.
