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

Sort of announced in July 2016, the most up to date Raspberry Pi Compute Module 3 (CM3) is assumed to reach the market in the near future. Last Oct computer equipment company NEC already announced a new variety of professional P and V Series large format displays that gracefully implant the RPi CM3 module. The new module, for sale in 2 options – CM3 and CM3L (lite) – will complement the CM1 module released before.

Specifications for the CM1, CM3 and CM3L SODIMM modules can be found in the data sheet obtainable on the RPi internet site

. Where the CM1 was driven by a BCM2835 processor (as used on the original RPi and RPi B+ models), the CM3 consists of a quad core 1.2 GHz BCM2837 processor, similar to 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 the person to connect his/her individual SD/eMMC product. The pinout of the CM1 and CM3 modules are identical but the CM3 module is one mm higher (31 mm).

Cost

The price of the new modules isn’t known yet, but as a CM1 is sold at roughly £20, a comparable price might be anticipated for the CM3.

Specifications

The CM3 is founded upon the Raspberry Pi 3 hardware and is intended for industrial use in order to provide a cheap approach for people to make printed products based upon the Pi hardware and software system. The Compute Module line is more compact and has less benefits and ports than a regular Raspberry Pi, allowing it to be to suit Internet of Things (IoT) products.

“The module uses a standard DDR2 SODIMM form factor, sockets for which are made by some makers, are conveniently available, and also are economical,” Raspberry Pi COO and hardware lead James Adams said in a blog post.

There are 2 versions of the CM3. Below are the technical specs for both:

Standard Version:

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

Lite Variant:

BCM2837 processor at as high as 1.2GHz
1GB RAM
SD card interface on Module pins for that reason a user can wire this up to an eMMC or SD card that they pick

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

Supplies essential power to the CM3
Enables you to program the CM3 Standard’s flash memory or to work with an SD card 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)
Supplies the required HDMI and USB connectors allowing you to have an complete system which can boot Raspbian (or the Operating system of your choice).

“This board presents both a starting template for those who want to design with the Compute Module, and a quick way to begin experimenting with the hardware, and building and testing a system, before you go to the cost of making a custom-made board,” Adam said.

The older Compute Module model will continue to be offered, for folks who wouldn’t like the CM3’s performance boost. As stated by the Raspberry Pi official magazine The MagPi:

“With several caveats, the CM3 may be used a drop-in replacement for the CM1 being that they are pin compatible; the CM3 is 1mm taller, yet, while the CPU can pull a great deal more current from the VBAT power supply line and definately will produce a whole lot more heat under heavy load.”
