I wonder what type of applications will come out of this.

For example, I want to build security cameras with Raspberry Pis, but I don't need audio output, USB, HDMI, etc...but I would need WiFi, camera unit, and power. But I doubt we'd see custom IO boards for specific applications such as this, and I don't think it'd be any cheaper than just buying a regular Pi.

Looks really cool but I'm slightly disappointed to see that when buying these Compute Modules in bulk they still each cost about the same as a single full Raspberry Pi (Version A). The Compute Modules do have 4gb of built in flash that the Version A doesn't have though.

I'll be interested to see how this progresses. With any luck, it'll open up a market of cheap, well-distributed SOMs, similar to the Pi opening up a market for cheap, well-distributed ARM/Linux Dev Boards. The situation's surprisingly similar: Powerful ARM Dev boards existed before the Pi, but the price was steep, they couldn't be found in traditional distribution channels, and the OS/Driver support was poor at best.…

You really see these being sold in Radio Shack? With Pis, all the average person needed was a regular keyboard, mouse & monitor to plug in. That's why it worked. That's all been thrown out here.

Nope, I don't see these being sold in Radio Shack. The world of electronics distribution reaches way beyond Radio Shack.

I mean: Before the Raspberry Pi, there were Linux-capable ARM Dev Boards, but the vast majority of them were niche items, over $150, and you had to call up the manufacturer and convince them to sell you one. (oh, and don't you dare use this in production without securing a larger purchase agreement!) Now, there's a proliferation of sub-$100 Linux-capable boards being sold by all the distribution houses, in large quantities, with no or limited restrictions on use in production.

I hope this move from the Raspberry Pi foundation does the same thing for OEM SOMs. Right now, there are only a handful of SOMs on Digikey/Mouser, most with fewer than 100 units in stock, all (that I can find) over $100, with zero community of support. Most of the companies with strong reputations in the market require a phone call before they'll even agree to sell you units for sampling.

And an additional 256MB (512MB versus 256MB for the Model A).

Earlier quoted context omitted.

My understanding is eMMC flash memory is an SD card soldered onto a board, so if anything that problem could be worse without the advantage of a removable card

It's very similar but often faster. The Odroid U2 uses removable EMMC storage which has an SD card adaptor, which I feel is a very good middle ground (most of the advantages of both with the disadvantage that the connector on the board is non-standard).

SD cards have different classes- without seeing specs, I'd be willing to bet that a Class 10 SDhc card is on par with this EMMC storage.

I'm a little disappointed that this isn't a compute-addon for the rPi that gives it some serious calculation power. Ah well .. guess I'll stick to the IMX platform for that ..

That was the first thing that came to my mind too. What kind of hardware specifically were you expecting and what kind of acceleration hardware there is generally available for these kinds of applications?

Well, in the case of the rPi, a swarm of CPU's with large RAM would be nice. Something 'unique' to plug the rPi into, which gives it a bit more oomph.

Well, I suppose this play to put the rPi "platform" everywhere, is to be expected. But I don't really see the appeal in this when there are already multi-core ARM DIMM's to be played with. This is clearly a brand play by the rPi folks, and after all .. why not..

There are really great cheap SOC's out there, in ARM land, to play with.

Just look at these guys: http://www.acmesystems.it/aria

Look, the rPi started off as a play-thing for kids, and there is now a valid rPi generation. It is expanding as a platform. But: in the industrial world, the rPi is a small fish. You can get an rPi precisely because some other industry has already driven the demand/price/costs down for it to be affordable/profitable to build a new brand around what is, a common industry practice/device mind-set.

Here in Austria, at least, any Conrad's has a "raspberry pi accessory" shelf. Sure, its Conrads .. but then again its Conrads. That is about as Big Mac Consumer as you are going to get.

I know of at least a few other places, here in Vienna, where you can get an rPi pretty much any time of day by vending machine. wtf, you're still using Radio Shack, lol.. ")

It looks like the module plus the I/O board costs $30 in large quantities. So aren't you really getting pretty much the same deal? I'm sure the modules alone will be cheaper.

Well, the existing RPi's GPU has 24 GFLOP capability, which is roughly the same as the GPU on the baseline i.MX6 (the Vivante GC2000). Now, a lot of that capability has historically been unavailable to RPi users, but they're slowly responding to pressure and opening up the GPU. But I also saw the headline and was hoping for some nice little GPU compute add-on the RPi. Oh well. I still think this is a very promising f…

Does the compute module have the GPU on it? Or is it on the connector board?
