Ras Pi foundation announces a new product: the compute module.

The compute module contains the guts of a Raspberry Pi (the BCM2835 processor and 512Mbyte of RAM) as well as a 4Gbyte eMMC Flash device (which is the equivalent of the SD card in the Pi). This is all integrated on to a small 67.6x30mm board which fits into a standard DDR2 SODIMM connector (the same type of connector as used for laptop memory). The Flash memory is connected directly to the processor on the board, but the remaining processor interfaces are available to the user via the connector pins.

While not yet what I imagined by only the name i.e a unit to build a shoebox-sized Beowolf cluster of 1K-RasPi-cores the new form factor and pin-out should make this endeavour easier (ahem... for someone skilled in PCB design, EE practician, and a soldering-fu master that has achieved enlightenment... not quite my profile).

    As far as soldering this thing, I would use lots of rosin-type flux and solder wick.

    I, personally, would look at brushing the component leads with solder paste, then carefully aligning the part, then sticking it in a toaster oven.

    I have heard about this method but I have never tried it. I heard about it in Circuit Cellar. Even collected several old toaster ovens to try doing it this way. I always thought I would have problems with cooking the board as well as its components, but have no practical experience to back up that belief.
