Measurement comparison between V2 versions

We have stopped selling non-Plus versions since October 2020. To avoid getting a bad clone, look for V2 Plus and Plus4 versions only.

Unofficial hardware variants

For SYSJOINT's NanoVNA-F V2, see http://www.sysjoint.com/en/content/?144.html

For BH5HNU's 3GHz NanoVNA-F development, see https://groups.io/g/nanovna-f

The following are the unofficial (clone) hardware versions that are tested to be compatible with the NanoVNA V2 firmware.

While we used to allow producing and selling the V2.2 design without royalties, clones from vendors that participate in unfair competition practices such as dumping will not get support from us and are not listed on this page.

Because of past disputes about unfair competition, we no longer permit Hugen/Zeenko from making and selling copies of the V2 PCB design and have issued a public statement in October 2020: https://groups.io/g/nanovna-users/message/17875
We currently wait and see if he will respect the wishes of the developers of a design he is making money from or if he will take your design and run with it. For all developers who are looking for a partner to produce and market your design, we recommend looking for a more trustworthy partner such as Seeed Studio, Elecrow, or Makerfabs, just to name a few.
Thank you for your understanding.
