The Raspberry Pi Compute Module is the perfect solution to embed Raspberry Pi functionality into your industrial design. The CM3 Compute Module is a follow on from the previous CM1, with an updated processor and increased speed.
The CM3 is a prototyping platform aimed at business and industrial users.
CM3 vs. CM1
The CM3 is the later version with various improvements to functionality. As we mentioned previously, there has been an upgrade to the on-board processor. The CM1 CPU runs at 700MHz while the CM3 offers an impressive 1.2GHz. The memory capacity has also increased from 512MB on the CM1 in comparison to 1GB on the CM3.
The CM3 is most comparable to the Raspberry Pi 3 Model B (896-8660) in terms of core functionality.
CM3 vs. CM3 Lite
The main difference is that the CM3 comes with eMMC Flash and the SD/eMMC, whereas the CM3 Lite board does not. However, the CM3 Lite (123-2012) is fitted with the appropriate pins for you to connect your own SD/eMMC device.
What is a Compute Module?
The Compute Module (CM3) is similar to the traditional Raspberry Pi boards, in that it houses the same core. It features the Broadcom BCM2837 SoC which is also available on the Raspberry Pi 3 Model B and the Raspberry Pi 2 Model B V1.2. The CM3 also features a 4GB eMMC Flash which is comparable to the SD card available on other Raspberry Pi boards.
The idea behind the Compute Module is that it is smaller and can be integrated into designs. This SODIMM module comes in a much more flexible form to be embedded into systems and other products.
How does it connect?
The CM3 Compute Module enables you to customise the connectors to your own specific requirements. The compact board measures just 67.6x31 mm (compared to the 85x56mm standard boards) and it fits onto a standard DDR2 SODIMM connector. The Compute Module offers compatibility with many GPIOs and interfaces through a 200-pin connector edge.
The CM1 is suitable for those who plan to create their own printed circuit board (PCB). However the CM1 I/O Board (136-3741) is also an ideal adapter to interface to get your CM1 Module set up.
Is the CM3 for me?
If you’re looking for something with a small form factor which you are able to customise to suit your designs, then the CM3 is an ideal tool. There is even a kit available (127-0226) containing the CM3, the I/O board and a power supply.
The Compute Modules are intended for more advanced users and will require more input to create your project. If you are looking for something a little simpler, you might be best to look at one of the traditional Raspberry Pi boards, for example the Raspberry Pi 3 B+ (137-3331).
