Overview
The LM811 combination module o ers coexistence for
Bluetooth® (Dual Mode) and WiFi operations, allowing the
host computer to wirelessly communicate with other
Bluetooth® and WiFi enabled devices.
This cost e ective module saves valuable PCB space within your product.
The LM811 module fully supports IEEE 802.11b/g/n/d/e/h/i
and Bluetooth® v2.0, v2.1, v3.0 and v4.0 standards.
Compatible with Linux (Kernel v4.3.6), Android 4.4 and Windows XP – 10 platforms.
The LM811 module also o ers low power consumption and an intelligent
coexistence mechanism, ideal for communicating with many wireless devices such
as tablets, smart phones and laptops.
