There's a list of specifications here: Raspberry Pi Model B+ and Model B Boards and Accessories | MCM Electronics

and here: Raspberry Pi Model A+ Board Features a 40-pin GPIO Connector, a micro SD slot, and Improved Power Management

A+ looks like a nice board.  I like the size: it finally fits in an Altoids box   US$20 price is very impressive.  With the 40-pin GPIO connector it becomes a good candidate for projects that would otherwise need BeagleBone.

Best thing about it is that it can fit in those smaller enclosures Altoids included !

It's all over the net now so no more point in hiding it ... I suppose the very existence of this thread means they think the same ..So far!

It's a shame that it still has connectors poking out all over the place and is using micro USB for power.

If it really sells for £12.50 it is very cheap.

Hard to slag it off too much when it's cheaper than a genuine Arduino

Noooo.... It only has 256mb of ram. I don't want to have to use a full model b just so I can get the extra ram. I hope they add an option to order a 512mb version for slightly more ram intensive applications. Apart from that it looks very nice.

Alas, that won't happen.

The units are quite cheap and that is achieved by doing mass-production with lots-of-the-same-units. Having all sorts of options no-tv-out for me, extra ram for you is going to make things more expensive. So if you need more ram, I'm afraid you'll have to get the bigger B+....

glad someone knows how economics works.

if you really really want 512 mb ram, desoldier the components off the b+. It is the same device. If you want to go to the extreme, disconnect the power from the usb chip. Then you (technically) have a model a+.

Haha! If you try moving the RAM chip, or CPU+RAM from the B (*) to the model A, and you make a nice write-up of what you did you'll get featured on "hackaday.com".... Either as "fail-of-the-week" or as a regular article... :-)

(wallarug: you're not completely clear: There are three ways about it that you're suggesting: 1) move the RAM chip off a "B" to an "A", 2) move CPU+RAM from a model B to a model A, 3) downgrade the "B" to an A by disconnecting the USB chip. (#)

(*) note: where I'm saying "model B", this includes the "B+", same goes for "A".

(#) This might no longer be possible with the B+: The PCB has (probably) not been designed to be "downgradable" to a model-A+. The "designed as downgradable" means that there is a "jumper" that allows you to connect the CPU-USB to the connector instead of to the ethernet chip. So disconnecting the usb-hub/ethernet chip will probably leave you without any USB on the B+.

Oh... On hackaday they predicted that it would take a week for someone to come up with power-measurements for the model A+...

I measured it on Tuesday but don't think it warrants a fully writeup for a hackaday article. My model A+  uses just under 100mA (about 95-97) when idling, but with a full-HD monitor connected. There are short peaks when the "SD active" led flashes, The peaks are around 150mA, so it seems as if my SD card (a trancend) uses about 50mA. Note that the current consumption depends on the exact voltage that you provide. By providing closer to 5.5V than 5.0V, the current consumption should also go down by about 10%.....
