2. GENERAL PRODUCT DESCRIPTION
Overview
The WE866C6 is a low power and low-cost WIFI/BT wireless module solution based on
Qualcomm QCA9377-3. It supports 1×1 IEEE 802.11a/b/g/n/ac WLAN standards and BT
4.2 + HS + BLE, enabling seamless integration of WLAN/BT and low energy. It is a perfect
companion solution for Telit cellular modules such as LE910Cx or LE920A4.
WE866C6 supports low-power SDIO 3.0 interface for WLAN and a UART/PCM interface
for BT. WE866C6 also supports BT-WLAN coexistence and uses the 2-wire ISM-LTE
coexistence interface.
