Pi 3 Power for Embedded Systems Designers

Product Announcement from RS Components, Ltd.


Love Pi 3's functionality but need something smaller for your embedded designs? Raspberry Pi's CM3 (Compute Module 3) is just 67.6 mm x 31 mm and fits into a standard DDR2 SO DIMM socket. Now embedded systems designers can integrate Pi power into more industrial-type applications.

The new Compute Module 3 family of products is available from RS now and includes:

  • Raspberry Pi Compute Module 3 (CM3)
  • Raspberry Pi Compute Module 3 Lite (CM3L)
  • Raspberry Pi Compute Module 3 IO Board (CMIO V3)
  • Raspberry Pi Compute Module 3 Development Kit (CM3 Dev Kit)

Raspberry Pi Compute Module 3 (CM3)

CM3 is the standard version of the latest Compute Module from the Raspberry Pi Foundation. It is pin compatible with the existing Compute Module (CM1) and features the same 64-bit quad-core 1.2GHz Broadcom BCM2837 as the Raspberry Pi 3 Model B. It also features 4GB eMMC flash memory and 1GB RAM.

Raspberry Pi Compute Module 3 Lite (CM3L)

CM3L is the 'Lite' version of CM3. It is exactly the same as CM3 but without the eMMC flash device. Instead, the eMMC/SD interface pins are routed to the edge connector for you to connect your own microSD card or eMMC device.

Raspberry Pi Compute Module 3 IO Board (CMIO V3)

A new version of the Compute Module IO board is available too - CMIO V3. This latest version of the break-out board includes a microSD card socket to support the Lite module (CM3L). Otherwise, it is the same as the original CMIO board.

Raspberry Pi Compute Module 3 Development Kit (CM3 Dev Kit)

If you want to get straight down to prototyping with CM3, this kit bundles together everything you'll need. It includes:

  • Compute Module 3 (CM3)
  • Compute Module 3 IO Board (CMIO V3)
  • Official Raspberry Pi Power Supply in white


Features and benefits

  • Open-source development board
  • Powerful latest-generation device
  • Provides low-cost development capabilities
  • Offers the same basic processing capabilities as Raspberry Pi 3 Model B
  • Identical pin-out to the original Compute Module (CM1)
  • Provides a starting point for the development of application-specific baseboards
  • Small footprint at just 67.6 mm x 31 mm
  • Extensive Raspberry Pi community for support
  • The Raspberry Pi Foundation guarantees the availability of CM3 and CM3L until at least January 2023
