Raspberry Pi Compute Module 4 I/O Board, PCIe Gen 2, Dual HDMI 2.0, Gigabit Ethernet with PoE, RTC, for CM4

The Raspberry Pi Compute Module 4 I/O Board (CM4IO) is the ultimate development and deployment platform for projects built around the Raspberry Pi Compute Module 4. Powered by the BCM2711 chip with an ARM Cortex-A72 processor, this board brings together a comprehensive set of interfaces to help you prototype and build real-world products with ease. It features dual full-size HDMI 2.0 connectors, a Gigabit Ethernet RJ45 port with PoE support, and two USB 2.0 sockets with headers for two additional ports. A standout addition over the standard Raspberry Pi 4 Model B is the PCIe Gen 2 socket, enabling expansion with compatible PCIe cards.

The board also includes dual MIPI DSI display and dual MIPI CSI-2 camera FPC connectors, a micro USB port for CM4 updates, a micro SD card slot for CM4 Lite modules, a standard fan connector, and an onboard RTC with battery socket and wake functionality. External +12V and +5V power connectors round out this feature-rich board, making it ideal for both product development and direct deployment with Raspberry Pi HATs.
