WIFI Module 5BK is a FCC / CE certified module that uses the same chipset (Realtek RTL8821CU) as WIFI Module 5B, so it is 100% compatible. IEEE 802.11ac/a/b/g/n WLAN and Bluetooth combo module with on-board 2.4Ghz and 5.8Ghz Dual band antenna.

Only one minor difference from the previous 5B model is that doesn’t have a CD-ROM mode. So, we can skip the usb-modeswitch tweak.

Works with ODROID series, Compatible with Android and Linux. (Please update your OS to the latest version if it doesn’t work.)
