1. for 5 multifunction machine, specially designed for 5. Modular design, simple assembly for quick use, large space, rich interfaces and strong scalability.2. Large space and strong scalability. There is enough space in the chassis to connect expansion modules, such as PoE modules, etc., and there is still room for cable routing, which is for obsessivecompulsive disorder.3. Lead out the Pi5 peripheral interface, support both front and rear power supply methods, each version comes with a Micro to adapter board, and support the lead out TypeC interface, and wiring terminals, so that the interface is not hidden deep in the chassis It is convenient for other peripherals to access the interface, and supports two power supply methods: one front and one back.4. Dual 4K HD output, each version supports dual interfaces and dual 4K video output5. Threedimensional air duct, efficient heat dissipation, reserved ventilation grid, and installing fans for better heat dissipation effectDifferent Batches May Have Differences In Product Appearance, Color, And Printed Characters, Which Will Not Affect The UseColour:As ShownMaterial:PCB+Aluminum alloyType: B:Pi5 Module BOXA,Gigabit Ethernet port, dual , dual 4K HD output (Type A PCle extended Gigabit Ethernet port)Package Contents:1x adapter board1x expansion adapter board1x button1x terminal block1x cable1set x screws1set x connecting wires1set x housing and white aluminum alloy baseOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
