Hello:
I just purchased a NanoVNA-H and a sticker on the back saying its Hardware Version 3.5. I was expecting to see a quick link to a Firmware version list, Change log and link to the firmware and download utility. Does this exist?

Which is the firmware version, what is the latest and should I bother updating?

Looking at the current firmware screen I see:
V 1.045 [p:101,IF: 12k, ADC: 192K, lcd 320x240, Built time Jan 30 2021.

Kernel 4.0.0

It has Platform STM32F072xb

Any help much appreciated. I am beginning to think I should have gotten a RigExpert analyzer.

Hello Brumey!

In the files section --->
/g/nanovna-users/files/Dislord%27s%20Nanovna%20-H%20Firmware
Last version for both - NanoVNA-H and NanoVNA-H4 from DiSlord.

Or here with change log

You have FW Version 1.0.45 from Hugen with big fonts. All FW versionen from DiSlord for
NanoVNA-H have small fonts.

Best regards
Vladimir

and important for beginner:
/g/nanovna-users/files/Absolute%20Beginner%20Guide%20to%20The%20NanoVNA

please compare two screenshots of Hugens 1.0.45 and DiSlord's 1.0.64

Version 1.0.45 is the latest firmware released by Hugen for his NanoVNA-H. It has a lot of features and I suggest you get used to using it before you even consider updating your firmware.

The Absolute Beginners Guide that Vladimir Lebedev posted a link to is very good reading and will get you started.

I own a RigExpert Analyzer and an MFJ-259B. They are simpler to operate but do not have all the features and capability of the NanoVNA which is also less money. If all you want to do is measure SWR of antennas the RigExpert has more features for that and has a minimal learning curve. I have an AA-55 Zoom and it works well except for the Bluetooth which has a well-known design defect that RigExpert will not fix.

Very Helpful.

If it's only the font issue and no major functional improvements, I might just not update it.

it's more, as fonts. please read change log to versions 1.0.50, 1.0.53 and 1.0.64:

Hello! congratulations on your purchase! It is very interesting to look at the PCB of your NanoVNA v3. 5! If of course it does not bother you! Sincerely yours!
