Raspberry Pi Compute Module 4

The Compute Module 4 (CM4), from Raspberry Pi, is a fast and powerful system-on-module (SoM) offering a range of connectivity and memory options for design engineers building embedded solutions. Key features include a small form factor, power efficiency, PCle support and a variety of multimedia interfaces. Its power and versatility make it useful for artificial intelligence, the Internet of Things (IoT) and a wide range of home and industrial automation applications.

The product is based on the Raspberry Pi Model 4B single-board computer, with an updated form factor accommodating interfaces such as dual HDMI, PCIe and Gigabit Ethernet, in a reduced footprint. Access to the processor interfaces and GPIO pins is provided via dual 100-pin high-density connectors. For flexibility, the device is available with different eMMC flash and DRAM density options, and with optional dual-band wireless connectivity. A ‘lite’ variant is available without the eMMC fitted.

Performance and connectivity features include: a Broadcom BCM2711 quad-core ARM Cortex-A72 64-bit processor clocked at 1.5 GHz; 1 to 8 GB of LPDDR4-3200 SDRAM and up to 32 GB of eMMC Flash memory; hardware codec support for H.265 (up to 4Kp60 decode) and H.264 (up to 1080p60 decode and 1080p30 encode); and an optional fully certified radio module, supporting dual-band IEEE 802.11 b/g/n/ac wireless networking and Bluetooth 5.0. An onboard electronic switch selects between an external or PCB antenna.
