1 Description

The SiP module M905 is a small size
module with antenna inside. The module
provides full function of Bluetooth 4.2
Low Energy in a tiny module via 52 pins
LGA Foot Print. The M905 module
provides everything required to create
Bluetooth 4.2 Low Energy product with
RF, baseband, MCU, qualified Bluetooth
v4.2 stack and customer application
running on a single IC.

M905 enables ultra-low power
connectivity and basic data transfer for
applications previously limited by the
power consumption, size constraints and
complexity of other wireless standards.
The low power consumption and excellent
radio performance make it the best solution
for OEM /ODM customers who require
embedded Bluetooth 4.2 Low Energy
feature, such as, IP camera, car key, sport
and fitness watch, mouse, led light bulb
etc.

For the software and driver development,
we provide extensive technical document
and reference software code for the system
integration.

Hardware evaluation kit and development
utilities will be released base on listed OS
and processors to OEM customers.
