This is the only official NanoVNA V2 group, please be aware!

This is the official support forum/user group for the NanoVNA V2, which is a low cost 3GHz T/R VNA (vector network analyzer). It is not based on ttrftech's NanoVNA design but a new from scratch design using 2 ADF4350 to cover up to 3GHz and Si5351 to cover down to 50kHz. Compared to the original ttrftech design, V2 uses only the fundamental signal for measurements and achieves higher dynamic range.

Warning about cheap underperforming clones

As of September 2021 there are many clones on the market. These clones do not go through any quality control and most perform badly. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts. If a clone is selling for much cheaper than the official store it will likely not meet specifications. 

All V2.2/V2_2 are clones! See official stores below and look for V2 Plus/Plus4 versions only to avoid getting a bad clone. We have stopped selling older versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

Where to buy

Official store

Note: All listings on Amazon that are not V2Plus4 are bad clones, please be aware!
Note: All listings on Amazon that are not V2Plus4 are bad clones, please be aware and don't be fooled by the reviews from over a year ago, most clones have since switched to salvaged or reject parts and are much more noisy that you are better off buying a V1 NanoVNA instead!

Name Release Date Remarks
V2 Plus4  
2020/10 4 inch display. 4x faster sweep (400 points/s). Up to 80dB dynamic range to 3GHz.
V2 Plus
2020/10    2x faster sweep (200 points/s). Noise improvements. PCB text still indicates "V2_2".
V2.2 2019 The earliest version of the V2 hardware. No longer sold. V2.2 has been discontinued since October 2020, and all V2.2 versions still on the market are clones. To ensure you get a supported hardware version, look for V2 Plus and Plus4 versions.
