The Raspberry Pi Compute Module 4 CM4 Router Carrier Board is an expansion board designed to enhance the capabilities of the Raspberry Pi Compute Module 4. It features two full-speed gigabit network ports that provide improved performance, reduced CPU usage, and heightened stability for extended periods of operation. The board maintains the classic GPIO pin header, allowing for the connection of various HAT boards, sensors, and cooling fans. Additionally, it includes a USB 2.0 interface for peripherals such as flash drives, keyboards, printers, and Wi-Fi modules.

An integrated OLED screen measuring 0.91 inches enables customization of the information display, adding a user-friendly touch to the boards functionality. The board supports the OpenWRT open-source router system, allowing it to function as a router after a straightforward setup process. It is also compatible with Raspberry OS, Ubuntu Server, and other Raspberry Pi systems, offering versatility for various applications, including retro gaming.

Equipped with a standard HDMI interface, the board allows for easy configuration and display of operational information. The robust performance of the BCM2711 quad-core 1.5GHz Cortex-A72 processor, combined with the extensive software support from the Raspberry Pi community, makes this board an excellent foundation for creating high-performance gateways, smart routers, and home IoT platforms. It can also be connected to peripherals to serve as a mini-NAS, wireless network bridge, or mini server, controllable via terminal.

For those requiring multiple LAN network ports, the use of a gigabit switch is recommended to expand the network ports without compromising internet performance. The boards 5V DC fan interface supports a cooling fan and is capable of PWM protocol, allowing for fan speed control through PWM signals. This board is versatile enough to be used as a router or for other applications, but please note that the Raspberry Pi board is not included.

Please be aware that the Raspberry Pi Compute Module 4 series is required for use with this board and is not provided.
