Very nice boards, but concerns about using them in products

I really like a number of these boards in terms of their features and price, but so far I cannot justify their use in released products in my Industry (Industrial Control).  I say this, as all of these and other generic controllers lack suitable industrial hardened power supplies, or transient protection/fusing, etc that are needed for long term reliability... the result is that additional boards, etc would be needed and then one has to determine if it would be cheaper to design a custom single board solution, as opposed to having multiple assemblies (the off the shelf board and one or more custom boards) and associated cabling.  Secondly, how does one mitigate long term support risk?  A number of the boards use devices that are not widely available and/or are consumer oriented and so design changes, etc are a real possiblity... the result is that support costs increase in order to support the different flavors of the boards.  Indeed, some of the boards have released design files so that one "could" remanufacture their own board, but this is also not a simple undertaking, as some parts may be specialized or have high minimum order quantities.  In my view I see these boards as excellent learning platforms, proof of concept vehicles, or even as reference designs that firms can use... but certainly nothing that I could use for my production needs.

What means SOM ?  

So these boards are also a way to get people famliarized with a certain kind of board or architecture and then be able to sell them the high end commercial application boards. 

That's good marketing!

I have an Artigo 1000 kit - for free if you want it

Hey, nice piece Cabe! Some great tech for next to nothing. Speaking of which, I have an Artigo 1000 kit (http://www.via.com.tw/en/products/embedded/artigo/a1000/) that I got from DesignWest (more on DesignWest in the coming days, standby). I've been sitting on it for a few years. I went to set it up as a simply webserver the other day only to find it's way outdated and no longer supported by Via Technologies. I could mess with it, but just don't have the time for some odd reason.

Anyone want it? It's a great little package and I can't just throw it out.... If you want it, and are based in the US, I can mail it to you: no charge (how's that for a deal?:). Just ping me at patrick.mannion@ubm.com.

All I ask is that you share with us what you do with it and how you did it. Deal? Just some photos and a description.

I think this is very much the equivalent of what the mini-ITX was some years ago for embedded PC based DYI type projects, or PC104 in th 90's. Some of them will go into volume, but very often it's used only for early stage proof-of-concept development work, which is great. For real commercial volume projects though, I think most of them end up with either a Computer-on-Module and a custom carrier, or a making a customdesign with the SOC on a single board. Having said that, if you can solve all of your application requirements with only one off-the-shelf board that is manufactured in volume, that will always be the most cost-efficient alternative, the same way you have a embedded applications where an embedded PC motherboard or SBC has all the functionality onboard that's needed.

Rick, I think they really help the SOM market. For example , the beagle bone helps create a great dev ecosystem , and then these guys[1] start offering a SOM with a processor from the same family(less capable),  at an attractive price point($27/1K)for 275MHZ,128MB flash/ram, etc.

Wrong photo for Parallella

The Parallella description has an extra copy of a Hackberry A10 photo.

Other than that, nice collection of boards!


[Edit: Thank you for correcting it, especially since Parallella is such a pretty board.]

The XU cost $149 now in pre-order state, and will be $169 afterwards.  Higher than your $100 price point, but to my mind still a bargain.

Commercial use

To what extent are any of these boards finding commercial use beyond the DIY world? Is the open source nature of them a drawback for volume commercial apps?

When I think of SBCs I think of Advantech, Kontron, Elma, GE, Mercury, etc. who mainly do higher end Intel and Freescale (Power) boards but are starting to move to ARM SoCs.

...these little single-board computers will motivate more young people to learn programming like the Commodore C64 has motivated me in the 1980s. Yes, it is not only possible to play games with computers. ;-)

The mind boggles...

When I started university in the mid-1970s we worked on both analog and digital computers. The main digital computer wa sin its own building -- we created out programs on punched cards and/or paper tapes. My mind boggles when I think that each of the SBCs discussed in this column could probably out-compute that room-sized beast...
