I just received a NanoVNA S-A-A V2. I want to read the measured data of the device (not control the device) from the serial port. nanovna-saver did not run on my Windows 10 computer (black window. tried 32 and 64 bit versions). I'd rather use my own code anyway.
Beware of cheap underperforming clones
As of 2022 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.
