Hello Dan,
??? Sorry for the delay , I have been? busy still trying to use various .ino files without sucess.
To answer your query; If you do a google search for "Si4432 module warning"? I think that
you will see the appropriate information. It is a forum message (though I don't know what forum) and shows three red PCBs (one works, one is poor and one is bad). Guess which ones I bought! There is also a blue PCB which is said to work.
??? Banggood do that one. So as I have got nowhere? trying to test the ones that I have I will order two from there in case I get back to this project someday.

Dan,
These are the ones I bought.? I bought 3, am currently using 2, they seem to work great.
The third I have removed the filter parts as per Erik's instructions, but haven't used it yet.
These seem to be the same modules as Erik is using:



Can't beat the price (at least when I bought mine, these were the cheapest I could find!).

Erik's build instructions say
??The SI4432 modules should be something like this:

That's an info page, the product you want is probably this one:
? ?

Good news:? cost of $2.60 USD (plus shipping)
Bad news: "Due to the quarantine of coronavirus, we will be closed until 10th, and starting to send order after 10th."

I tried downloading the RF22 Arduino library they point to in that info page.
Full of object oriented C++ to create mesh networks and stuff, I'm sure it's very cool.
But not my cup of tea.

Tony, not trying to hijack your thread - but which modules are the good one? Anyone know - like an eBay/Amazon link or something? There must be a million of those things!

Spur reduction uses small shifts of the first IF.
As the Spurs move around and the real signals are stationary any algorithm that is able to detect this will work

Simplist is a minimum hold algorithm
Or a running average.?

This is not yet implemented in the local code

Hi.

Is there any information available about how the spur reduction works in TinySA???

The ILI9341 display has arrived and I have it working with my ESP32.? With the faster updates on the local display it is easy to see spurs as they move if the RF frequency changes, and was wondering about adding spur reduction into the Arduino code.

Even if it is too complex for an Arduino, it would still be interesting to understand how it works.

Many thanks

I decided to create a github account create a MS Visual Studio Dev Essentials subscription to review the VS versions to download.? Well... ~900MB for the 2010 Express seemed better than the Visual Studio Community 2015 ~4GB for now ISO.? So downloaded and installed and began reviewing another applications code I was shown. Seems easy and intuitive like VS 2003.NET and 2005 Pro (more like).

However, I am wanting to review this apps code (tinySA) and am guessing is derived from the Tapr-VNA... though haven't loaded and read into yet.??

Any advice regarding any differences between the tinySA before I start reading into??

I'm not planning to make any modifications and if I do, I'll read into github processes more and do what looks like a fork/branch into my jafinch78 account.?

Time to study up the differences between 2003/2005 versions and learn some C# as I've not programmed in before (only VB or C++ with VS) as well as learn how to interface input devices.? Thanks in advance for your time.

Doh.. silly me, you are right!
It works fine.
It actually a USB3 port on my HP laptop..? it is called a "data only" port too, I was afraid it wouldn't
supply any power....
Thanks Ion,

I needed a maple mini board for another project and found this one to be a reliable clone.

I am powering my tinySA from a 5V bench power supply and on-board 3.3V regulator (Arduino Nano powered by USB).

After init, the supply shows about 110mA drain, during and after a sweep it shows only about 70mA.
It would be nice if it would be under 100mA so it could be powered exclusively by USB (100mA max, right?).
I realize Signal Generator mode would probably be higher, I could use an external supply in that case.

Any info?
Thanks and 73,

I bought the same item from a "US" seller (didn't want to wait - LOL).?
Thanks Eric.

Hello Erik,
???? I? really don't like to add even more to your "to-do" list, but as and when you can, I wonder if you can add at least one of the early .ino files to the github (or Forum files) collection.
???? I have two reasons: One is that I prefer to start with the simplest version, and only add the bells and whistles when that is working.? The other is that I want to change it (if? necessary) to provide a tester for single Si4432 modules, because of the stories about the ones that I bought only giving an output of -15dBm!
???? In case you reply that the later versions would perform the earlier functions, I will add that the early file (that I have lost!) compiled ok and ran in an Arduino Nano. But the later files with the rotary encoder, attenuator and display just give me chains of the usual incomprehensible (to me) error messages!
I know that you have done enough already, so thank you either way.

I bought these on Ali Express. A little more powerful than the stm32f103 based boards and about the same price.?

This should work

For that price... I'd consider the more powerful Photon boards.? I just found this even better priced version that matches the Tau price point you noted:

Here's the Photon Particle link from their store:

If for some reason you're stuck on Ardunio Uno boards there's a Sparkfun Redboard:

Or i'd consider an ESP32 clone, though I think those are on Aliexpress for cheap or maybe the RaspPi version more homegrown from Michigan:

I invested in an AtomicPi for starters... though am thinking I'm going to invest in one of those Photon boards since reads impressive.?
