nanoVNA hardware

thanks to hugen, NT7S Jason, hwalker, Rune / 5Q5R

the original nanoVNA by edy555 has elegant RF design

Other hobbyist VNA, antenna analyzer, and software defined radio designs
share many of these design concepts.
edy555's open source design was in limited distribution as a kit.

nanoVNA-H commercialized by Hugen reduced cost and enhanced usability

At least 5 nanoVNA-H implementations
black, shields, USB-C
Hugen's @ and close clones

white, micro USB "gekko"
initially most available on eBay

black, unshielded, USB-C, missing CH0 script
AKA "Worse clone"
Variations may come
  • with or without batteries,
  • battery leads soldered or by connector,
  • better or worse calibration kits,
  • SMA connectors fully soldered or not,
  • different firmwares,
  • calibrated (touchscreen and/or OSLT) or not.
  • rear cover shielded or not
  • Many vendors may ship different units over time.

    NanoVNA-H V2
    V2 will use two synthesizers that overlap for up to ~ 3 GHz measurement range

    Diagram from a preview @ RTL-SDR.COM:

    Note the number of switches, making component selection and board layout more critical.

    "NanoVNA 2"
    Different from "NanoVNA-H V2"...
    From original nanoVNA inventor Tomohiro AKA edy355, per this message
    J.R.R. Tolkien: "Those who approve of courtesy (at least) to living authors"
    nanoVNA in name only
    Larger screen, different processor & RTOS (so obviously firmware), perhaps some similar commands.
    This has its own group for good reasons.
