AJMRTC 6221CPUC wireless combo module is powered by Realtek RTL8821CE chip, combining dualband WLAN and Bluetooth 5.0 function on a compact circuit board. It follows IEEE 802.11 a/b/g/n/ac WiFi standard with 1T1R antenna chain, supporting both 2.4GHz and 5GHz frequency bands, peak WiFi speed reaches 433Mbps. WiFi communicates via PCIe bus, while Bluetooth runs over USB interface with PCM channel reserved for Bluetooth audio transmission, simplifying hardware circuit design for developers. Integrated metal shielding housing suppresses internal RF interference and enhances antiinterference performance. Compact dimension 16×12×1.8mm saves board space, widely applied in IPTV boxes, POS terminals, industrial control equipment, smart screens and other embedded devices. Operating voltage is DC 3.3V, external IPEX antennas are required for normal signal reception. Corresponding RTL8821CE driver installation is mandatory to unlock full WiFi and Bluetooth features. Only wireless module is included; antennas, host motherboard and other accessories are not contained in package.
