Raspberry Pi Compute Module 3 (CM3) aims to gadgets

Sort of announced in July 2016, the new Raspberry Pi Compute Module 3 (CM3) is assumed to hit the market quickly. Last Oct computer equipment company NEC previously announced a new spread of professional P and V Series large format displays that seamlessly embed the RPi CM3 module. The new module, available in two flavors – CM3 and CM3L (lite) – will complement the CM1 module launched before.

Specs for the CM1, CM3 and CM3L SODIMM modules appear in the data sheet offered on the RPi website
. Where the CM1 was driven by a BCM2835 processor chip (as utilized on the original RPi and RPi B+ models), the CM3 contains a quad-core 1.2 GHz BCM2837 chip, like the RPi 3. It provides 1 Gigabyte of LPDDR2 RAM and 4 Gigabyte eMMC Flash. The ‘L’ version is a CM3 not having eMMC Flash, permitting the customer to link up his/her individual SD/eMMC device. The pinout of the CM1 and CM3 modules are exactly the same but the CM3 module is one mm higher (31 millimeters).


The buying price of the new modules isn’t known yet, but because a CM1 is sold at roughly £20, a similar price could possibly be expected for the CM3.

Based upon :


The CM3 is based on the Raspberry Pi 3 hardware and is created for industrial use in order to supply a cost efficient opportunity for people to make customized products based on the Pi software and hardware system. The Compute Module series is scaled-down and has less functions and ports than a regular Raspberry Pi, so that it is suited to Internet of Things (IoT) products.

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

There are 2 versions of the CM3. Listed below are the specifications for both of them:

Standard Version:

BCM2837 processor 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 for that reason an end user can wire it up to an eMMC or SD card of their choice

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
Permits you to program the CM3 Standard’s flash memory or to work with an SD card on the Lite version.
Connect to the processor interfaces in a slightly more friendly fashion (pin headers and flexi connectors, just like the Pi)
Offers the essential HDMI and USB connectors allowing you to have an entire system which can boot Raspbian (or perhaps the OS of your choosing).

“This board presents both a starting template for those who want to design with the Compute Module, and a fast way to get started on trying out the hardware, and building and testing a system, before you go to the expense of making a made to order board,” Adam said.

The older Compute Module model will still be offered, for individuals that wouldn’t like the CM3’s performance boost. As reported by the Raspberry Pi official mag The MagPi:

“With a couple of caveats, the CM3 can be utilized a drop-in replacement for the CM1 considering they are pin compatible; the CM3 is 1mm taller, on the other hand, while the CPU can pull a lot more current from the VBAT power source line and will eventually deliver a great deal more heat under heavy load.”
