It's a totally different beast. Completely different design,PCB,machined
housing., Etc.
The only thing in common are that it's a VNA and it's relatively
inexpensive.
Litevna is a trademarked name as is nanovna.
They're not related

Please do not associate the name NanoVNA with LiteVNA

Both are inexpensive VNAs but one has nothing to do with the other.

What distinction are you making? The LiteVNA has only just appeared so
information is a little scarce, but it appears to be another nanovna
variant. Do you have reason to believe that it's not?

Hello, this is my S-A-A v2 clone and work, yours don't work? I think the
different groups support you not the device.
Device support is from the seller.
On this group or other there hare people ready to help other this is the
reason for the support group.
Ask your question about your device and someone came to help you.
There is a lot of good people on the NanoVNA different groups ready to
help not worry.
Best regards.
Francesco.

Hi Anthony,
This is the support group primarily for the original version of the
NanoVNA, H & H4 devices but members have a mix of the various devices and
experiences.
Also - please search the forum messages - there is a lot of info. I wrote
a how to search doc that is the 1st link in the Wiki. The trick is to start
wide and narrow down the search terms - and don't give up after 2 searches.

20 or so messages back there are 2 links to the SAA support groups.

Anthony, a few observations:

The wiki in this group makes the following observations that I find
relevant:

Section 1.1.5 for hardware shows that the "nanorfe.com" website is
associated with the nanovna 2-0 , aka OwOComm's S-A-A-2
Section 1.1.6 covers the Nanovna-H4 , and lists it as different hardware
from the SAA2

Also, the nanovna.com website points back to this group for support,
while the nanorfe.com site points back to a different group here on
groups.io, the NanoVNAV2 group.

So I associated the question of "approved vendor" in this group with the
wiki in this group, and the nanovna.com

Different hardware, both using the name "Nanovna" --- hmmm, what could be
confusing about that?? (slight grin)

Walter, et al,

Both pages seem to contradict each other. This page
says the following:

*Official stores:*


- *Official store on Tindie*
<>
- *Official store on Taobao (NanoVNA V2 唯一官方淘宝店)*
<>


*The following stores are selling illegal clones.*

*The clones sold by these vendors do not have permission from the original
developers and are violating the non-commercial license of the design
(CC-BY-NC-SA).*


- *Banggood*
- *R&L electronics - still selling clones despite being asked not to
by the original developers*

*Important: Zeenko is selling S-A-A-2 based designs without permission and
in violation of our non-commercial license, with exaggerated
specifications. The original V2_2 design was open sourced to help hobbyists
learn, but Zeenko's actions force us to close source later designs
<>. Please reconsider supporting
this vendor.*

Do you know which has the correct information or am I missing something. I
did purchase the SAA 2N unit from R&L. Also I will point out that I did a
firmware upgrade with NanoVNA 1.0.69 package. There are seven files in the
package. I first tried V2Plus but that seemed very erratic. I then
flashed V2 480x320 v 1.0.69 and that works fine. It did add much more in
the selections in the flowchart than what came out of the box at R&L. Not
to say there was anything wrong with it, but the newer firmware had more. I
can also see the data on my PC using NanoVNA-QT, which I guess is expected.
The next thing is to see how well it performs in certain functions. Remains
to be seen.

Regards,

Anthony (N2KI)

That's what I just did , and bought H4 from R&L Electronics. (Ordered via
the web on Nov 21, arrived at my home Nov 26). Very satisfactory experience.

Since you expressed a preference for Ebay/Amazon, you might wish to use
the link they provide for "AURSINC" on Amazon.

The SAA uses a binary programming protocol, not dfu, so I don't know what
help files you are referring to.Please refer to docs that reference the SAA
series of devices specifically and refer to the SAA user groups for info on
programming the device.
Search the forum messages for SAA and binary
This topic has been covered a few times here.

wrote: So I have spent quite some time trying to get the SAA-2N to
connect to my PC using a number of different help files. None of which
worked. There are a number of missalignments to what the help files say to
do and what is actually appearing.

For starters, the drivers were installed without any errors. This was
confirmed by the Device Manager display not indicating a yellow triangle.
When the VNA is connected to the USB port, it shows up as being on Com 8,
specifically USB Serial Device (COM8).

Second, the help file says to enter DFU mode by the following path (per
flow chart) "Config" > "DFU". That path does not exist in my unit. My
best guess is to enter "Config" > "Bootload" but I can not verify this as
it is not in the help file. Can someone confirm this?

Next, when in the bootload screen, the DfuSe v3.0.6 still does not see the
VNA. Also I will point out that there is no listing in the Device Manager
saying STM Device in DFU Mode, yet the drivers installed correctly. When I
try to reinstall the drivers, Windows says the best drivers are already
installed.

Next, when looking at the Version screen, there is no Version listed. It
just says Version:
Underneath Version is shows a Build Time of June 9 2021 -17:36:19

So is there a help file that I am missing? I appreciate if anyone can
clarify this procedure.

Thanks!
