LiteVNA 64 - is sensational, I can recommend it with a clear conscience

73,
Sebastian

Hello Siegfried,
The Deepelec NanoVNA-F uses slightly different electrical design to the original "edy555" NanoVNA and so does not use the original PCB layout. So there are no "unused" crystal pads.
Therefore the Deepelec hardware is not compatible with the "normal" NanoVNA software and so misses out on the wonderful work by DiSlord and others.
But the superior screen and current Deepelec firmware works for me. (although I would like some of the latest cable measurement capabilities.)
Either way, these little boxes are absolutely wonderful and are a testament to the brilliance of some of those amongst us.
Cheers...Bob Vk2ZRE

Your chip looks like a 5351 since it has the right markings and was produced in 2000. See description below. The chips are now readily available again with stock at DigiKey and Mouser. It is a 10 pin MSOP so not hard to replace if you are careful. Before replacing I would check a couple of things. Make sure the 26 MHz. clock input is running. Probe the SCL and SDA data lines and see if they are active and I2C traffic is going to/from the chip.

David,

Thanks for the info! I am investigating the LiteVNA 64.

Thank you for the reply.

Loading back to the oldest 0.4.5-4, has brought me back to the original status as my son and I got it a year ago as per the attached image.

More info. I can still attach as via serial and get the info from the board. Basically it seems to be coming up, but not working on the touch and jog wheel.

Ok Just to clear up my previous message. It is a NanoVNA-H as marked on the
board but it is the unit with the 4" screen, so using the
NanoVNA.H4.v1.2.00.dfu is correct. As for the other comments that the failed
chip "si5351 init Failed", I no longer get the message after upgrading the
firmware, however the jog wheel and the touch screen are not active. I have
attached an image of the unit to show the screen after the upgrade.

NanoVNA's made by Hugen with a 2.8" screen are -H and with a 4" screen -H4. Copies or modifications of his PCB layout and circuit design often use the -H/H4 markings but are not the same PCB layout and often use different components. Your device seems like one of these copycats.

The 4" screen is not the only difference between a -H and a -H4. The -H4 has a SD card, improved power supply, and component changes to give better performance. The biggest difference is the CPU chip used in the -H4. It was upgraded to accommodate the 4" screen and has more flash memory, RAM and onboard peripherals.

When the -H4 first came onto the market 3 years ago it did not need all the extra flash and RAM and still used 101 data points. Over time DiSlord and Hugen added capability to the firmware like 401 data points, SD card support and more functionality that required this extra flash/RAM.

The problem for copycat products of the -H4 is that they often used a CPU which could accommodate the 4" display but did not have the high end 303 processor. This situation got worse with the shortage of semiconductor chips during the pandemic. Th other issue was the si5351 clock chip. This part became rare and Hugen and others started using a MS5351 Chinese clone. Here are a few previous threads discussing these issues.

/g/nanovna-users/topic/85648812#24744

/g/nanovna-users/topic/69974156

So given this background information what do you do? A common problem observed when loading the wrong firmware is to see a si5351 init fail message or a frozen screen with no traces displayed on the screen. I suggest you try loading an old version of the Hugen firmware that still used 101 data points and had limited new features. See if that works and then try to update the firmware by successive versions until it does not work anymore.

Here is a link to the oldest 0.4.5-4 >>

Next try version the February 2020 version and if that works the 1.0.45 version

Both devices are available with a 4 inch screen, although I normally use a Windows 10 PC running NanoVNA-App or sometimes NanoVNA-Saver. The device that I purchase would need to be compatible with these software applications.
Other than the wider frequency range of the SeeSii device, I would be interested in hearing from other list members about their experience with either (or both) of these devices.
Thanks in advance!

Would the ZeenKo LiteVNA 64 suit? It works well but I've not specifically tested over 2-4 GHz. I think it would work with one of those apps. There's a group where you could ask:

Hello Fred,

Re the "new version" of the -101, I think you are getting confused by his comment (in red) on the DeepVNA-101 page stating "2022 New version. Added Rotary Encoder and RTC functions".
This was actually comparing the -101 to the -F. The -101 was released in March 2022.
The two devices are basically the same except for the rotary encoder instead of push buttons (on the HW V3.1) and the added function of the RTC (which would be nice to have on the -F).

Al -
My flagpole antenna would be for portable, temporary use such as Field Day and Parks On The Air.

And the price is a major concern - there are $1200 20 foot flagpole antennas, but not for me! (Besides, 20 feet is not enough for reasonable efficiency. 33 feet would be a lot more productive.)

Which/what OCF flagpole did you scan with the NanoVNA?
Thanks!

Where does he imply a revision to the hardware? I can't find anything like that. Can you give the URL where you saw it? Actual hardware changes are relatively rare.
The firmware, however, seems to be in continuous improvement. I have upgraded mine several times.

Nuts - that put me back into procrastination mode, wondering what new features would be included???
I've got a RigExpert AA-230 Zoom for general antenna work, so the NanoVNA would mostly be a fun toy (also need to measure some common mode chokes).
Anyone know what changes will be included in the new upcoming "101"??

Fred,

The same folk released the "DEEPSDR 101" radio receiver with a number of defects which were widely discussed and reported. In spite of many (polite) requests there has been no firmware update forthcoming, let alone any offer of hardware updates to fix the issues.

A number of us feel very disappointed about this, not to mention feeling that we have wasted our money (not a cheap device).

If it were me, I would consider getting a different device.

73.

Yes, I found it. I needed to go to "more" and reread the entires. I found Node with "MS5351" and "Si5351" as options. I chose MS5351. Not where I expected it - especially with the number attached to the Alpha portion.

Once again, thank you, larry

Hi
Using Ubuntu Linux, I use dfu-util -a 0 -D *
* go to my Downloads directory and copy the file name
This then puts the filename and path into the terminal command
Then just press Enter - and voila!

I would like to use the same for updating my new nanoVNA H4 . Presently,

Using the tinySA, I delete the version number. i.e. tinySA............bin

the above worked fine so long as I:
a) used the correct firmware (tinySA and tinySA Ultra are different)
b) deleted the firmware version numbers from tinySA...............bin to
tinySA.bin

I tried;

dfu-util -a 0 -s 0x08000000:leave -D nanoVNA \ H4.dfu
and it did not work! I think I need:
NanoVNA H4 v1.2.19.bin to do as outlined above. Is there a way of
converting:
NanoVNA H4 v1.2.19.dfu to NanoVNA H4 v1.2.19.bin ?? If not, where do I
get NanoVNA H4 v1.2.19..bin ?

Thank you for any help, larry

Thank you again!! Worked like a charm!

I don't see where I should tell within the Firmware I have (M) type. I have:
