Raspberry Pi Compute Modules 4 (CM4)

Raspberry Pi Compute Modules 4 (CM4) feature a compact form factor with 55mm x 40mm x 4.7mm dimensions for deeply embedded applications. These System-on Modules (SoMs) contain a processor, memory, eMMC flash, and supporting power circuitry. This configuration includes a quad-core Arm^® Cortex^®-A72 processor, dual video output, and a wide selection of extra interfaces. The electrical interface is via two 100-pin, high-density connectors. The CM4 series enables users to leverage the Raspberry Pi hardware and software stack in their own designs. Raspberry Pi Compute Modules 4 are offered in 32 variants with a range of RAM and eMMC flash options.

The modules are available with or without wireless connectivity. On the CM4 Lite version, the eMMC flash is not fitted. These modules feature dual-video output, hardware video decode at up to 4Kp60, up to 8GB of RAM, Gigabit Ethernet, USB 2.0, and dual camera interfaces. The Compute Modules 4 are used in embedded applications.
