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.

Image	Name CONFIG>VERSION	Firmware support	Firmware download	Features
	V2 Plus4 V2.4 Latest version Buy	20201013 stable 20210425 experimental	Download (stable) Download (experimental)	4" display 4x faster sweep (400 points/s) Frequency range extended to 4GHz 90dB dynamic range to 1GHz, 80dB to 3GHz

	V2.2 Deprecated / No longer sold	20201013	Download	2.8" display The earliest NanoVNA V2 hardware version. Obsolete. All V2_2 from 2021 on are clones which are not officially supported.

• The V2_2/V2.2 model has reach end of life and is now deprecated. We no longer provide any technical support for clones of this model. The V2 is replaced by the V2 Plus and V2 Plus4 that perform better and are actively maintained. Owners of a genuine V2 from the official stores can contact us to obtain a discount if they wish to acquire a V2 Plus or a V2 Plus4 model.
• You can identify which NanoVNA V2 variant you have using the table above. Select CONFIG > VERSION in the menu on your device. This will show an about screen with the device name on top which you can look up in the table above.
• Ensure the correct firmware variant for your hardware version is used, otherwise your device may fail to boot.
• Only the above 3 hardware versions are official, but some unofficial versions (listed below) also have firmware support.

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.
