Product Description

1.Introduction
 

The 6221B-UUC is a low-cost and low-power consumption module which has all of the

Wi-Fi functionalities. It is based on Realtek RTL8821CU chipset, a highly-integrated

IEEE 802.11a/b/g/n/ac MAC/Baseband/RF WLAN and Bluetooth Baseband/RF single

chip. For Wireless LAN (WLAN) operation, this module supports 1-stream 802.11ac

solution with USB2.0 network interface controller. For Bluetooth operation, it supports

Bluetooth 2.1/4.2.
 

6221B-UUC complies with IEEE 802.11a/b/g/n/ac standard and it can achieve up to a

speed of 433.3Mbps with single stream in 802.11ac to connect to the WLAN.
 

This compact module is a total solution for a combination of Wi-Fi and BT technologies.
