Description
This Waveshare Metal Box (A) provides a durable and functional enclosure for your Raspberry Pi Compute Module 4 IO Board. Engineered for efficient assembly, it transforms your CM4-IO-BASE-A into a compact and protected mini-PC, ideal for various embedded applications. The enclosure ensures all necessary cut-outs align precisely with the IO Board’s connectors, maintaining full peripheral access.
A key feature of this metal case is its integrated cooling solution. It comes equipped with a dedicated cooling fan and features strategic airflow vents, significantly enhancing heat dissipation for stable, long-term operation of your Compute Module 4. This active cooling capability is crucial for performance-intensive tasks, ensuring the CM4 operates within optimal temperature ranges even under continuous load.
Furthermore, the design prioritizes expandability. Despite its protective qualities, the case ensures the standard 40-pin GPIO header remains fully available. This allows developers and makers to easily connect various Raspberry Pi HATs and expansion boards, extending the functionality of their CM4-based system without compromise.
