N400B for Orange Pi 4B
N400B Accessories
N400B with antenna



Since Orange Pi 4B is out of stock, we no longer sell this product, but we can provide bulk orders: MOQ: 500pcs

This is Geekworm design metal case ONLY for the Orange Pi 4B, not for Orange Pi 4. You can refer to N400 if you want a metal case for Orange Pi 4;

It reserves all the interfaces of the orange pi 4 motherboard, supports the cooling fan, supports the extraction of the GPIO cable, and also reserves 2 antenna holes for you to replace the antenna that comes with the motherboard.

You can buy another antenna to replace the PCB antenna

I can't understand why the naming of orange pi is so confusing. . . .


  • Nice appearance
  • Good heat dissipation
  • Reserved GPIO cable hole
  • All ports and slots of the case can match with orange pi 4B board perfectly
  • Good wifi signal, reserves many round cooling holes on the side of the case, almost no weakness for the WIFI signal;
  • 2 antenna holes are reserved to facilitate the installation of external antennas
  • High quality metal material with surface galvanized process;
  • About the cooling fan, the fan label marks 12V but it is also ok to use with your orange pi board.
