Although the Raspberry Pi's original purpose was as an educational tool, many enthusiasts have used the (mostly) open source hardware at the heart of home automation, robotics projects, and other embedded systems. In light of this success, the Raspberry Pi Foundation has unveiled the Raspberry Pi Compute Module, a miniaturized version of the Raspberry Pi sans IO ports that fits onto a single SO-DIMM module. The Compute Module houses the BCM2835 SoC, 512MB of RAM, and 4GB of flash memory and can be paired with custom designed PCBs.

The Compute Module will initially be released along with an open source breakout board called the Compute Module IO Board. The IO Board is intended to be an example to get users started and to help them along the path of designing their own customized PCB. The IO Board has a SO-DIMM connector that the Compute Module plugs into. It further offers up two serial camera ports, two serial display ports, two banks of 2x30 GPIO pinouts, a micro USB port for power, one full-size USB port, and one HDMI output. The Raspberry Pi Foundation will be releasing full documentation and schematics for both the Compute Module and IO Board over the next few weeks.
Using the Compute Module and a custom PCB, the embedded system can be smaller and lighter than then traditional Raspberry Pi.

The Raspberry Pi Compute Module and IO Board will be available as a bundle (the "Compute Module Development Kit") from Element14 and RS in June. Shortly after the development kit launch, customers will be able to purchase the compute module itself for $30 each in batches of 100 or slightly more for smaller orders.
More information can be found on the Raspberry Pi blog. Here's hoping the industrial / embedded market successes will help fuel additional educational endeavours and new Raspberry Pis versions in the future.
