The Armor housing "BLOCK ACTIVE" for thatRaspberry Pi® 4 B is your ideal partner when it comes hard on hard and gets really hot. The aluminum-based housing protects the Pi from heat and impact from the top and bottom. This makes it ideal for difficult environments. It is designed in such a way that it does not need more space than the Pi alone would require and thus enables the use in already existing projects. The additional active dual fan assembly combined with a corresponding "channel milling" creates an additional cooling effect under extreme loads. https://elecena.pl/product/28015796/joy-it-armor-case-for-raspberry-pi-4b-aluminium-and-block-active 2025-03-12 https://elecena.pl/product/28015796/joy-it-armor-case-for-raspberry-pi-4b-aluminium-and-block-active 2025-09-17
