Nanovna v2 plus 4 main board

Beware of cheap underperforming clones

As of 2023 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.

See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 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.

Hi,
I was measuring an antenna with the nanovna .
At the same time I was transmiting with another antenna.
As a result the mxd8641 got burned and also some parts of the main board are destroyed
It looks almost imposible to repair the main board

Does anyone know where to buy a main board replacement?
Nanovna model is V2 plus 4

Thanks and Regards
Arturo
