Pi Zero Build for sBitx Available

 

All -
?
I've added a sBitx SD card image for the Raspberry Pi Zero. ?
?
The same methods apply to writing the SD card image as for the Pi 4 ?
?
?
This SD Card image contains v4.301 64 bit sBitx software and the sBitx Toolbox preinstalled. Please note that there is no DSI port for the built-in touch display. You will have to purchase a Mini HDMI to HDMI Adapter to use a HDMI compatible monitor or enable VNC and use it headless. The Pi Zero has some additional limitations such as once microUSB port so you may need an adapter to connect a USB mouse or keyboard. The resources on this hardware prevent the effective use of resource intensive, 3rd party applications and web browser.
?
This is simply for experimentation and no support will be provided by me. It is a lower cost alternative for those who want to use it.

Hello JJ

Does this also have Rx / TX enable pin via Pi IO ?

It works with sBitx hardware via GPIO for TX/RX
 

Is this for the Pi ZERO or the Pi ZERO 2 W ?

When will the SD Card image for the Raspberry Pi 5 become a standard as the Pi 5 is the most current Pi with more improvement in the works such as RAM and SSD which will enable even faster processing which I am convinced will make the SBitX even better as more code will be written to take advantage of the improved processing. the future has arrived. Next we need an improved quadrature detection to fully exploit the SDR feature capabilities inherent in the SBitX architecture.

The 64 Bit Image for the Pi 4 also works fine with the Pi 5. I don't work for HF Signals and cannot answer the question about when they will incorporate the new technology in their product. We've successfully used Pi 5 in the sBitx line and have done the research as posted on the Discord server.

Pi ZERO 2 W. I don't have access to the older processor.
 

Update on Pi Zero 2W testing... I CAN run 3rd party apps with a remote display without too many issues. For example, I am using WSJTX with it X-11 forwarding via MobaXTerm and it seems to run great. This is a viable option and may work with the Pico on zBitx for display rendering as well. I need to test QSSTV and see how well it performs.

There's probably a lack of shading here, because I see such a bright screen at IF above 85.

The sBitx is still delivered with a Raspberry Pi 4. There is currently no communication from the producer that this will change since it is fast enough for the intended task. Farhan also stated here that even the much slower Raspberry Pi Zero 2 can do the job so I do not think a Raspi 5 will become standard soon.

I also don't think that switching to a Pi 5 really improves anything if you only want to use the sBitx as Radio.If you want it to do more, like replacing your Shack PC for example, only then you start talking about PI-5 NVME, actvie cooling etc. That is also the way I am headed, but for the radio part alone, a Pi 4 is plenty fast.

There is nothing to be gained in moving to pi5 except of course twice as much heat. You will neither receive more signals nor transmit further. Unless a new mode comes out that needs LLM grade processing, I cant see the need for even more than Pi Zero 2W. Our limitation is the amount of bandwidth that we process : 25 KHz. For this, we have four CPUs running at 1.5GHz, that more than 100,000 instructions per signal sample.
Surely, we can consume more CPU instructions making snazzy user interfaces. But even then, not really much more.
For now, I am developing the software on a Pi Zero 2W. I do everything that the sbitx and the zbitx is capable of and more (I run a streaming internet radio station too on my rpi zero, and gpredict for sats, vi, gdb) it works flawlessly.

The sBitx is still delivered with a Raspberry Pi 4. There is currently
no communication from the producer that this will change since it is
fast enough for the intended task. Farhan also stated here that even the
much slower Raspberry Pi Zero 2 can do the job so I do not think a Raspi
5 will become standard soon.

I also don't think that switching to a Pi 5 really improves anything if
you only want to use the sBitx as Radio.If you want it to do more, like

PI-5 NVME, actvie cooling etc. That is also the way I am headed, but for
the radio part alone, a Pi 4 is plenty fast.

Just went to buy a Pi Zero 2W but they are sold with no connector.? What type of
connector and how does it plug into the radio?? Maybe a picture?

You can buy the Pi Zero 2W with header pins presoldered..?

Here is the connector you need.

And here is the one with headers..

I will try to get a picture for you.

The Zero 2WH has a header pre-installed for about $3 more
