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

Sort of announced in July 2016, the latest Raspberry Pi Compute Module 3 (CM3) is assumed to go to the market in the near future. Last Oct . PC equipment manufacturer NEC previously announced a new array of professional P and V Series large format displays that easily embed the RPi CM3 module. The new module, available in two options – CM3 and CM3L (lite) – will complement the CM1 module released some years ago.

Specifications for the CM1, CM3 and CM3L SODIMM modules come in the data sheet available on the RPi web-site
. Where the CM1 was powered by a BCM2835 chip (as employed on the original RPi and RPi B+ models), the CM3 provides a quad core 1.2 GHz BCM2837 processor, like the RPi 3. It has 1 Gigabyte of LPDDR2 RAM and 4 Gigabyte eMMC Flash. The ‘L’ version is a CM3 without eMMC Flash, allowing for the end user to add his/her personal SD/eMMC system. The pinout of the CM1 and CM3 modules are identical but the CM3 module is one mm higher (31 mm).


The price of the new modules is not known yet, but as a CM1 retails at roughly £20, a equivalent price could very well be predicted for the CM3.

Technical Specs

The CM3 is founded on the Raspberry Pi 3 hardware and is suitable for industrial use in order to give a cost efficient solution for individuals to make custom products based upon the Pi software and hardware system. The Compute Module product line is smaller sized and has less functions and ports than a standard Raspberry Pi, rendering it perfect for Internet of Things (IoT) products.

“The module uses a standard DDR2 SODIMM form factor, sockets for which are made by several makers, are simply accessible, and are low-cost,” Raspberry Pi COO and hardware lead James Adams mentioned in a post.

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

Standard Version:

BCM2837 processor chip at up to 1.2GHz
1Gigabyte RAM
4Gigabyte of on-module eMMC flash

Lite Model:

BCM2837 processor at up to 1.2GHz
SD card interface on Module pins consequently a user can wire it up to an eMMC or SD card that they decide on

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

Delivers needed power to the CM3
Permits you to program the CM3 Standard’s flash memory or to use an SD card on the Lite version.
Connect to the processor interfaces in a slightly more friendly fashion (pin headers and flexi connectors, similar to the Pi)
Provides the required HDMI and USB connectors so you have an complete system that can boot Raspbian (or the Operating system of your choosing).

“This board gives both a starting template for those who want to design with the Compute Module, and a quick way to begin trying out the hardware, and building and testing a system, before going to the fee for fabricating a tailor made board,” Adam said.

The older Compute Module model will still be provided, for individuals that do not require the CM3’s performance upgrading. As reported by the Raspberry Pi official magazine The MagPi:

“With several caveats, the CM3 may be used a drop-in replacement for the CM1 as they are pin compatible; the CM3 is 1mm taller, nonetheless, while the CPU can pull far more current from the VBAT power supply line and will definitely make much more heat under heavy load.”
