On Saturday Asher had this hardware in his booth at the Dayton Hamvention. I did not take a photo but this screenshot is from his presentation at FDIM. It was pretty small. I really like the tiny built-in screen with the ability to control everything from a larger remote device.

Also, the order of operations is that the sBitx app must be opened first, then wait 20-30 seconds before opening the 3rd party app.

Hi Carlo.

Here are the correct settings for both apps.






You should see power output on the sBitx app when it is opened.

It also points to the GIT where the details about the hat are.
basically its for the person that can literally cook their own hardware
from the ground up.? By "cook" I mean assemble by copying the zbitx
design or go off in a different direction.

That means a lot of the design and build is in "your" lap and for many
that's a large task requiring electronic skills.? That and a very complete
understanding of the sBitx how and why.

Please use the forum, offline and private will go to bit bucket.

I still don't see any more of this than the digital part of sBitx. The information is too vague.
I'll wait for more data to appear on it.

Also check this thread -

/g/BITX20/message/111381

addendum to my previous message:
According to my knowledge, the drawing described as sBitxHat corresponds to the digital part of sBitx, the difference is that the experimental amateur can add his own idea to make it a usable and working device.

If you are waiting for a response from dx stations, then make a well-functioning antenna (without a tuner) and enjoy the 20 Watt output power. At the same time, experience when there is a good spread in which direction, then success will not be missed.

Hi Nick,
It seems to me that your information about sBitx is a little lacking.
In the title, you write about sBitx Hat, until then about sBitx. There are a few things I can say about sBitx.
The RPi 4B device is sold with 2GB of RAM, but it is advisable to use it together with 4GB of memory for more comfortable operation. The device was first produced with the addition of DE, of which 150 units were produced.
This was the first sample of further development.
?To date v2 and v3 have been released.
The difference between the latter two can be seen in the final stage.
v2 was released with an IRFZ24N and v3 with an IRF510 FET power stage.
IRFZ is more sensitive to overvoltage, while IRF can also be used at 13.8V.
There are no other essential differences in the hardware view.

As for the software, the v2 struggled with several childhood illnesses.
Since the middle of November 2023, with the release of the v3 version of the software, several modifications have been made in the following months thanks to those who know how to program. We are currently on version v3.02.

The software was installed on the then 32-bit Debian 10 OS, whose support ends this year, so Raphael and W9JES installed the sBitx software on the latest 64-bit Debian 12 (Bookworm) OS. W9JES went further by making it available and creating an additional ToolBox for better usability. You can reach all of these by entering the keywords in the search engine in the topic, then you will find the contact details. But if you wait a bit, there will surely be someone who will give you an exact link. W9JES is currently working (in addition to his work) on the development, you can read more about it in the messages he started.

You don't have to install it from the beginning on the Debian OS, because the best software is currently available in the form of an image.
That's it in short.

Because there is some confusion as to which schematic applies, why not use an ohmmeter to verify which pin is which? The five volt regulator (7805) on the Raduino board connects directly to the Gnd and 5V pins. The center pin on the 7805 is Gnd (as is the mounting/heat sink tab). The other two pins are 12volt input and 5volt output.? It would be best to be sure, before applying power.

The schematic showing the wiring of the second nano has some issues. ?The pin #’s should be the same on both nanos, but they are not. ?Also, not sure about the black and red wires that connect to the lcd display socket (P2) just above pins 1 & 2 where the Nextion connects. ?Is there a better schematic somewhere?

Hello -

I'm new to the list and to most things BITX. I have the sBITX hat given out at FDIM and am interested in dipping my toe into the water and seeing what happens.? Right now I'm trying to gather information.? Do I need to bide my time, or is it out there?? I get a sinking feeling when I hear the words: "It's all there on GitHub."??

I've looked at sBITX.net which seems to be a project from about a year ago. Is this essentially the same project, more or less??

I've also seen Farhan's .? Is this essentially the project described at FDIM?

I was looking at purchasing a Pi Zero 2 W for the project, but a couple of questions come up.? Do I install male pins and plug the Pi directly into the board? Or would that cover up some needed pins, so I should be thinking ribbon cable?? Are there photos anywhere that show how the thing goes together?

I see some discussion of loading a code image onto a memory card. Does this mean I do not need to buy a card with the OS (Raspian?) on it?

Thanks for any guidance & 73-

Nick, WA5BDU

Thank You JJ!

Robert

Sorry about the outdated link. The screen brightness control is now part of sBITX Toolbox which is located at ?

Gyula,

Soory that I posted this question on this posting. I just saw a few other people discussing the ways to control the temperature, a ways back in the posting so I thought I would ask instead of starting a whole new post.?

Thank your for your help.

David,?

Thank you for your help also. I think the information between the two of you should do the trick.

Thanks again, 73,
Robert
