Frequently Asked Questions

What is the primary function of the Compute Module 4 I/O Board?

The CM4 I/O Board serves as a baseboard for the Raspberry Pi Compute Module 4, transforming it into a versatile development platform. It exposes various interfaces like HDMI, USB, Ethernet, and PCIe, making the CM4 accessible for prototyping and integration into custom embedded systems. It simplifies interaction with the CM4's core capabilities.

What power requirements does the CM4 I/O Board have?

The CM4 I/O Board typically requires an external 12V DC power supply for standard operation. However, a 5V supply can be used for less power-intensive applications. It also supports Power over Ethernet (PoE) with a compatible HAT and power source, allowing both data and power through a single Ethernet cable.

Can I use standard Raspberry Pi HATs with this board?

Yes, the Compute Module 4 I/O Board includes standard 40-pin Raspberry Pi HAT connectors. This allows you to integrate a wide range of existing HATs for added functionality, such as sensors, motor controllers, or specialized communication modules. PoE HATs are also supported for network-powered solutions.

What is the purpose of the PCIe Gen 2 x1 socket on the board?

The PCIe Gen 2 x1 socket is a crucial expansion feature, enabling the connection of high-speed peripherals. This includes NVMe SSDs for fast storage, additional Ethernet controllers, or other PCIe-based expansion cards. It significantly enhances the CM4's capabilities beyond its built-in interfaces, opening up advanced applications.

How do I update the eMMC on a Compute Module 4 using this I/O Board?

The I/O Board provides a dedicated Micro USB socket for updating eMMC variants of the Compute Module 4. By connecting this port to a host PC and configuring the CM4 into USB boot mode, you can use Raspberry Pi's rpiboot tool to flash new operating system images or firmware directly to the CM4's eMMC storage.
