This board used is motherboard to The Compute Module 3 and the Compute Module 3 Lite :Only the Raspberry Pi compute module io board v3 is included but we are trying to give all the info needed to be known about raspberry pi compute module io board v3 and its accessories.
the Raspberry Pi 3. has a Broadcom BCM2837 System-on-Chip (SoC) which features a quad-core processor clocking in at 1.2GHz and is supported by 1GB of RAM. Pretty impressive given the size and cost of the device, not to mention the enormous software stack and community resources that are behind it. As we said, you’re probably already aware of this, but what you may not know is the Pi 3’s little brother; the Raspberry Pi Compute Module.
The original Compute module was released in 2014 and was designed to bring the power and versatility of the Pi to a smaller form factor which was better suited to industrial and commercial applications. By stripping away all of the hardware ports and leaving the raw BCM2837 with all the required supporting circuitry, it allowed developers and designers to pick and choose what features they wanted to implement, along with breaking out the full potential of the BCM2837 chip. It had the same specs as the Pi boards did then which was only 512MB of RAM and approximately 10x less processing power than the Pi 3.
But believe it or not, 2014 was 3 years ago now, and 3 years is an eternity in the tech world. So Raspberry Pi gave the Compute Module an overhaul to bring it up to spec with the Current Raspberry Pi 3. So the new Compute Module 3 (CM3) brings a spec bump, and an addition to the Compute Module 3 family in the form of the Compute Module 3 Lite (CM3L).
CM3 vs. CM3L
Stable and Mature Platform
The best thing about the Raspberry Pi Compute Module 3 is that it is a Raspberry Pi. It’s a mature platform and has been tested and refined by millions around the world. The Raspbian operating system is stable and snappy, with the new Pixel update giving a truly modern UI. Once it’s up and running, the CM3 runs just a well as the Pi 3, which is a very good thing (the Pi 3 is awesome!).
The CM3’s DDR2 SODIMM form factor makes it incredibly easy to implement into designs as sockets are readily available and cheap, and whilst the CM3 is an extra millimetre taller than its predecessor (30mm vs 31mm), it’s still only a third of the surface area of the Pi 3 (Model B+) and being less than 4mm thick, it’s as slim as they come. The total dimensions are 31mm x 67.6mm x 3.7mm.
Supporting Circuitry and Peripherals
Speaking of implementation, if you’re looking at using the CM3 or CM3L in a design, you’ve already got a solid platform with all the required supporting circuitry onboard. You don’t have to worry about the complex design of using the BCM2837 from scratch but instead, can focus on expanding the peripheral ports as your project requires. The BCM2837 actually supports more hardware peripherals than the standard Pi 3 has accessible (due to size constraints), so all 200pins of the SODIMM edge connector breaks out power along with:
1x HDMI 1.3a
1x USB2 HOST/OTG
1x DPI (Parallel RGB Display)
1x NAND interface (SMI)
1x 4-lane CSI Camera Interface (up to 1Gbps per lane)
1x 2-lane CSI Camera Interface (up to 1Gbps per lane)
1x 4-lane DSI Display Interface (up to 1Gbps per lane)
1x 2-lane DSI Display Interface (up to 1Gbps per lane)

CM3 vs. CM3L
The Compute Module 3 and the Compute Module 3 Lite are almost identical in every way except that the CM3 has 4GB of eMMC flash storage, whereas the CM3L does not. Instead, the CM3L breaks out the bus pins for the SD/eMMC so that you can implement your own storage off-board. Depending on your application, the onboard storage might be perfect, whereas, for high storage scenarios, it would be limiting, and more advantageous to implement external storage.
Compute Module 3 IO Board
In order to use/develop with the CM3 or CM3L, you’ll need the IO Board which breaks out all the pins and has connections for HDMI, power, USB, camera and displays, plus more. It’s a fantastic board, and well designed, however, the drawback is that unless you already have a physical implementation for the CM3/CM3L, the module itself is useless without the IO Board.
