Raspberry Pi Compute Module 3 (CM3) targets on consumer products

Sort of announced in July 2016, the most recent Raspberry Pi Compute Module 3 (CM3) is considered to go to the market very soon. Last Oct PC equipment manufacturer NEC already announced a new variety of professional P and V Series large format displays that flawlessly implant the RPi CM3 module. The new module, for sale in two flavors – CM3 and CM3L (lite) – will complement the CM1 module introduced before.

Specifications for the CM1, CM3 and CM3L SODIMM modules are located in the data sheet found on the RPi internet site
. Where the CM1 was based on a BCM2835 CPU (as employed on the original RPi and RPi B+ models), the CM3 posesses a quad-core 1.2 GHz BCM2837 central processing unit, similar to the RPi 3. It includes 1 GB of LPDDR2 RAM and 4 GB eMMC Flash. The ‘L’ version is a CM3 without having eMMC Flash, allowing for the buyer to link up his/her individual SD/eMMC system. The pinout of the CM1 and CM3 modules are identical but the CM3 module is one mm higher (31 millimeters).


The price of the new modules is not known yet, but since a CM1 retails at around £20, a equivalent price can be predicted for the CM3.

Technical Specs

The CM3 is founded upon the Raspberry Pi 3 hardware and is intended for industrial use in order to supply a less expensive opportunity for people to make tailored products based on the Pi hardware and software system. The Compute Module line is scaled-down and has less benefits and ports than a standard Raspberry Pi, making it suitable for Internet of Things (IoT) products.

“The module uses a standard DDR2 SODIMM form factor, sockets for which are made by several makers, are comfortably obtainable, and are economical,” Raspberry Pi COO and hardware lead James Adams claimed in a blog post.

There are 2 designs of the CM3. Below are the specifications for both of them:

Standard Version:

BCM2837 central processing unit at to a maximum of 1.2GHz
1Gigabyte RAM
4Gigabyte of on-module eMMC flash

Lite Version:

BCM2837 processor at to a maximum of 1.2GHz
SD card interface on Module pins thus an individual can hook this up to an eMMC or SD card that they select

Both models can be slotted into a newly released Compute Module IO Board V3 (CMIO3) which lets you conduct the following:

Presents necessary power to the CM3
Helps you program the CM3 Standard’s flash memory or to make use of an SD card on the Lite version.
Connect to the processor interfaces in a a tad bit more friendly fashion (pin headers and flexi connectors, much like the Pi)
Offers the needed HDMI and USB connectors to ensure you have an full system that can boot Raspbian (or the Operating system of your preference).

“This board provides both a starting template for those who want to design with the Compute Module, and a faster way to begin experimenting with the hardware, and building and testing a system, before going to the money necessary for fabricating a tailor-made board,” Adam said.

The older Compute Module model will continue to be offered, for many who have no need for the CM3’s performance turbocharge. As per the Raspberry Pi official mag The MagPi:

“With a couple of caveats, the CM3 can be utilized a drop-in substitute for the CM1 being that they are pin compatible; the CM3 is 1mm taller, having said that, while the CPU can pull far more current from the VBAT power source line and will generate a great deal more heat under heavy load.”
