geerlingguy and simonw really amaze me at how well and consistently they cover their respective spaces of interest. Great content, easy to read, and thorough! I'm sure there are others doing deep reporting like this on their own subjects. I'd love to read them too.
So it could be possible to make a small portable screen device with this, or maybe not because (I think) the RPI is not optimized to work on a battery.
I would prefer a touchscreen with it.
I am not talking about a smartphone, because smartphones are often more powerful, more expensive. I would just prefer a device to do simple computing, with full access to the OS.
Smartphones tend to have android and powerful hardware, and a 4G or 5G antenna. I would just be happy with wifi and enough power to run some C or python code.
I am just curious what is the cheapest screen device that is possible to make with this, as long as it has wifi, a touch screen and be completely open. So far RPI is nice, but it's not really what I want.
"But unlike all the other Compute Modules, the CM0 has castellated edges like a Pico. That way, a company integrating this into their product can just pick and place it and solder it onto their main PCB, instead of working with more delicate board-to-board connectors."
But wasn't the board-to-board slide-in connection the whole point with other CM models?
at a previous job we went with the previous generation SODIMM CMs for this reason. they didn't honor their stocking pledges though. typical broadcom things
It seems to be more that they are simultaneously launching and killing the product.
Sounds like they entered into a contact to develop and sell the CM0 to several large manufacturers who happen to all be in China, hence the launch. But then discovered the supply of ram chips that it uses is extremely low (they apparently stopped manufacturing them years ago) and they want to direct as many of them as possible towards the Pi Zero 2.
So we will probably see a follow up to both later, and the CM0-B (or whatever they call it) will be more widely available.
Those boards have a lot more on the board than just the cpu. At a minimum they have power conditioning and ram, usually also storage. A lot of what you pay for with an sbc is that routing and layout. If it’s got WiFi as well, you could be paying for the testing that goes into rf micro strips and potentially certifications on em emissions.
It is, of course possible to do all that yourself, but the system on module exists, because this integration has value that people are willing to pay for.
Unfortunate name, as "CM0" is a common abbreviation for the ARM Cortex-M0 core.
Browsing the web on here is almost completely out of the question, since it only has 512 Megs of RAM
How far we have fallen... a quadcore 1GHz CPU and 512MB of RAM seems like ample computing power for those who have been very productive on PCs with far less.
Jeff - can you please stop with the clickbait titles and the dramatic, bug-eye YouTube video thumbnails? You’re better than that. We will read your stuff and subscribe anyway don’t worry.
You can buy this - as well as the actual CM0 (Cortex-M0) from AliExpress although keep in mind it’s probably a knockoff chip and you likely won’t be able to debug it without a Segger or something.
