Raspberry Pi release their CM3 compute module

The Raspberry Pi is a name that is well known amongst creators and computer developers the world over, becoming a tool that is often referred to as the best device to learn the basics of computer science. 
Now several iterations of the Raspberry Pi have been released, selling widely outside of its intended “learning market” purposes and have been used in the creation of IoT devices, amateur robotics and for use in countless other enterprises. The Raspberry Pi is currently known as the world’s best-selling British computer, with the original model selling over 5-million units. 
Raspberry Pi release their CM3 compute module, which offers as much power as the Raspberry Pi 3 for prices as low as $25. This device has 2x the amount of RAM as the original CM1 and has 10x the CPU power, making this new version significantly more powerful. 
This device uses a DDR2 SODIMM form factor, which allows it to be used by various manufacturers using the existing DDR2 interface standard.

The CM3 will come with two different versions, with both using a BCM2837 processor that runs at up to 1.2GHz and 1GB of RAM. The CM3 will have 4GB of on module eMMC flash, with the CM3L (Compute module 3 Lite) coming with no eMMC memory and a built-in SD card interface on the module pins so the user can wire up their own eMMC or SD card storage solutions.  

With this new board, the Raspberry Pi Foundation will also be releasing a new IO board, the Compute Module IO Board V3 (CMIO3), which allows developers to program their module and experiment with the hardware, removing the need for them to design and manufacture their own custom motherboards during early development.  

Further details on the CMIO3 design board can be found below. 


   We are also releasing an updated version of our get-you-started breakout board, the Compute Module IO Board V3 (CMIO3).

This board provides the necessary power to the module and gives you the ability to program the module’s Flash memory (for the non-Lite versions) or use an SD card (Lite versions), access the processor interfaces in a slightly more friendly fashion (pin headers and flexi connectors, much like the Pi) and provides the necessary HDMI and USB connectors so that you have an entire system that can boot Raspbian (or the OS of your choice).

This board provides both a starting template for those who want to design with the Compute Module, and a quick way to start experimenting with the hardware and building and testing a system before going to the expense of fabricating a custom board.

The CMIO3 can accept an original Compute Module, CM3 or CM3L.


The Raspberry Pi CM3 will be available for $30 and the CM3L will be available for $25, with the price of the original CM1 module reducing to $25. Full design guidelines for these new boards can be found here.
