Raspberry Pi Compute Module 4 Mini Dual Gigabit Ethernet Mini-Computer (23852)

The Raspberry Pi Compute Module 4 Mini Dual Gigabit Ethernet Mini-Computer (23852 ) is a kit that contains everything you need to build a dual Gigabit Ethernetmini-computer for the CM4.

This kit enables you to build a minicomputer that has two Gigabit Ethernet connectors. This allows for a fast and stable network connection, which can be useful for a variety of applications such as network devices, servers, routers, and more.

The kit includes all the necessary components to assemble a minicomputer, including an expansion card with two Gigabit Ethernet connectors, a power adapter, a case, cables, and other accessories. In addition, it supports the Raspberry Pi Compute Module 4, which is installed on the expansion board, adding the processing power and capabilities of the CM4 to the minicomputer.

With this kit, you can build your own dual Gigabit Ethernet minicomputer based on the Raspberry Pi Compute Module 4. It provides flexibility and customization for a variety of projects that require a network connection with high speed and reliability.

* For reference only, CM4 is NOT included.
