Raspberry Pi launches CM5 module

Raspberry Pi has launched its long-awaited compute module, the CM5. This is a system on module that delivers the power of Raspberry Pi 5 in a form factor ideal for embedded applications.
The CM5 module measures 55 mm × 40 mm × 4.7 mm and is priced from $45. It uses the same 2.4GHz Broadcom BCM2712 quad-core Arm Cortex-A76 processor as the Pi 5, with dual 4Kp60 HDMI output, Gigabit Ethernet, optional fully-certified wireless module providing WiFi and Bluetooth connectivity, and a variety of RAM and eMMC flash options. There are 4 × M2.5 mounting holes.
The CM5 module adds I/O interfaces for more flexibility and providing a greater breadth of options for product and application design and cost-sensitive applications is available without eMMC flash. Also available to assist product designers is the Raspberry Pi Development Kit for Compute Module 5 for prototyping embedded designs. This combines a Compute Module 5 and Compute Module 5 IO Board. There is also a finned heat sink for the module.
The module has already been used in several designs from Seco, Revolution Pi, Kunbus and TBS but is now on general availability.
- Raspberry Pi prepares its CM5 module
- $7 wireless RISC-V Raspberry Pi Pico W2
- Pi5 moves to disaggregated architecture
Compute Module 5 is mechanically compatible with its predecessor, Compute Module 4, exposing all signals through a pair of high-density perpendicular connectors, which attach to corresponding parts on the carrier board.
Memory options for the CM5 are 1GB, 2GB, 4GB, 8GB LPDDR4-4267 SDRAM with ECC or 0GB, 16GB, 32GB or 64GB eMMC flash memory.
There is a PCI Express 2.0 interface with one USB2.0 port and two USB3.0 parts supporting simultaneous 5Gbps operation. There are up to 30 × GPIO supporting either 1.8V or 3.3V signalling and peripheral options for UART, SPI, I2C, SDIO and DPI. There are also up to four PWM channels and three GPCLK clock outputs as well as two HDMI ports and two four lane MIPI ports for displays and cameras
There are a small number of changes to the pin-out and electrical behaviour of the module, mostly associated with the removal of the two two-lane MIPI interfaces, and the addition of two USB 3.0 interfaces.
“But Compute Module 5 is only part of the story. Alongside it, we’re offering a range of new accessories to help you get the most out of our new modular platform,” said Eben Upton, CEO of Raspberry Pi.
“Every generation of Compute Module has been accompanied by an IO board, and Compute Module 5 is no exception,” he said. “The Raspberry Pi Compute Module 5 IO Board breaks out every interface from a Compute Module 5. It serves both as a development platform and as reference baseboard (with design files in KiCad format), reducing the time to market for your Compute Module 5-based designs.”
