Overview

CM-8821CU is a WLAN 11ac and Bluetooth combo Module, provides a
single USB interface to host, which fully supports the features and functional
compliance of IEEE 802.11b/g/n/a/ac standards. Bluetooth v2.1, v3.0 and v4.2
standards. It supports up to 433Mbps high-speed WLAN network connections
and Bluetooth protocol stack.

CM-8821CU Bluetooth controller complies with Bluetooth core specification

v4.2 and supports dual mode(BR/EDR+AMP+low Energy Controllers). It is

backward compatible with previous versions including v2.1+EDR and v3.0+HS.

Both BR/EDR and LE can operate simultaneously.

CM-8821CU provides a complete solution for a high throughput

performance integrated wireless LAN and Bluetooth module, and is targeted at

competitive superior performance, better power management applications.
