Raspberry Pi Compute Module 3 (CM3) aims to consumer products

Sort of announced in July 2016, the new Raspberry Pi Compute Module 3 (CM3) is assumed to go to the market quickly. Last Oct . PC equipment company NEC already announced a new range of professional P and V Series large format displays that faultlessly implant the RPi CM3 module. The new module, obtainable in 2 variants – CM3 and CM3L (lite) – will complement the CM1 module introduced some years ago.

Specs for the CM1, CM3 and CM3L SODIMM modules may be found in the data sheet accessible on the RPi site
. Where the CM1 was based upon a BCM2835 chip (as utilized on the original RPi and RPi B+ models), the CM3 includes a quad-core 1.2 GHz BCM2837 central processor, like the RPi 3. It includes 1 Gigabyte of LPDDR2 RAM and 4 Gigabyte eMMC Flash. The ‘L’ version is a CM3 without having eMMC Flash, which allows the end user to link up his/her personal SD/eMMC device. The pinout of the CM1 and CM3 modules are identical but the CM3 module is one millimeter higher (31 mm).


The money necessary for the new modules isn’t known yet, but because a CM1 is sold at somewhere around £20, a very similar price may well be expected for the CM3.

Technical Specs

The CM3 is founded on the Raspberry Pi 3 hardware and is for the purpose of industrial use in order to supply a cost effective solution for consumers to make printed products based on the Pi hardware and software system. The Compute Module line is smaller sized and has less functions and ports than a regular Raspberry Pi, rendering it well suited for Internet of Things (IoT) products.

“The module works with a standard DDR2 SODIMM form factor, sockets for which are made by several makers, are conveniently available in the market, and additionally are cost-effective,” Raspberry Pi COO and hardware lead James Adams explained in a post.

There are two designs of the CM3. Here are the specifications for both of them:

Standard Variant:

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

Lite Version:

BCM2837 processor at up to 1.2GHz
Sdcard interface on Module pins and so a user can connect it up to an eMMC or Sdcard of their choice

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

Offers essential power to the CM3
Helps you to program the CM3 Standard’s flash memory or to use an Sdcard on the Lite version.
Access the processor interfaces in a a little bit more friendly fashion (pin headers and flexi connectors, similar to the Pi)
Offers the necessary HDMI and USB connectors in order that you have an entire system that can boot Raspbian (or the Operating system that you choose).

“This board presents both a starting template for those who want to design with the Compute Module, and a quick way to start trying out the hardware, and building and testing a system, before you go to the money necessary for fabricating a tailor-made board,” Adam said.

The older Compute Module model will still be made available, for individuals that don’t need the CM3’s performance boost. Based on the Raspberry Pi official magazine The MagPi:

“With a couple of caveats, the CM3 can be utilized a drop-in alternative to the CM1 since they’re pin compatible; the CM3 is 1mm taller, nonetheless, while the CPU can pull far more current from the VBAT power line and will definitely deliver significantly more heat under heavy load.”
