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.

3.2" display VNA firmware update

simone 2021/05/03 02:08

Hello,

I flashed on my nanoVNA with 3.2" display the following firmware version: nanovna-v2-20201122-v2_3_2.bin . It ends by v2_3_2.bin, I guess because it is for the 3.2" display.

Online there are newer firmware versions, the latest is 20210425, but they ends by v2plus.bin or v2plus4.bin. Can I use them for my 3.2" device? If not, can somebody add to the repository the 3.2" version, please? The repository URL is: https://nanorfe.com/downloads/20210425

Thank you in advance for your help.

Regards,
Simone

Dear Simone,

i tried to help you, but you don't believe me and you ask the same question in the other forum.

1. I told you how to check if your V2 has FPU or not. Please see attached screenshot ( CONFIG--->VERSION)

2. I have sent you the current and the best firmware with the accompanying text from the programmer DiSlord.

I have tested ALL FW since the first release 20200328. 20201122 is not good, bugs!

3. I explained that the FW for V2 with 3.2 inch display is the same as for 2.8 inch - these displays have the same chipset and resolution 320x240 pixels.

It's OK?

With best wishes
Vladimir Lebedev

Dear Vladimir,



Thank you very much for helping me, I appreciate it a lot.



I asked the same question in the V2 forum in the hope somebody adds the new
releases also for 3.2 inch display. Otherwise the people with a device like
mine will miss all the great firmware upgrades.



I am sorry if you thought I do not believe you, I trust you and I thank you
for your very appreciated support.



Have a nice day,

Simone
