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.

Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: Any changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate this
equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may
cause undesired operation.
This device and its antenna(s) must not be co-located or operating in conjunction
with any other antenna or transmitter.
IMPORTANT NOTE:
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with
minimum distance 20cm between the radiator & your body.
IMPORTANT NOTE:
This module is intended for OEM integrator. The OEM integrator is still responsible
for the FCC compliance requirement of the end product, which integrates this
module.
Appropriate measurements (e.g. 15 B compliance) and if applicable additional
equipment authorizations (e.g. Verification , Doc) of the host device to be addressed
by the integrator/manufacturer.
IMPORTANT NOTE:
This module is intended for OEM integrator. The OEM integrator is still responsible
for the FCC compliance requirement of the end product, which integrates this
module.
20cm minimum distance has to be able to be maintained between the antenna and
the users for the host this module is integrated into. Under such configuration, the
FCC radiation exposure limits set forth for an population/uncontrolled environment
can be satisfied.
Any changes or modifications not expressly approved by the manufacturer could void
the user's authority to operate this equipment.
USERS MANUAL OF THE END PRODUCT:
In the users manual of the end product, the end user has to be informed to keep at
least 20cm separation with the antenna while this end product is installed and
operated. The end user has to be informed that the FCC radio-frequency exposure
guidelines for an uncontrolled environment can be satisfied. The end user has to also
be informed that any changes or modifications not expressly approved by the
manufacturer could void the user's authority to operate this equipment. If the size of
the end product is smaller than the palm of the hand, then additional FCC part 15.19
statement is required to be available in the users manual: This device complies with
Part 15 of FCC rules. Operation is subject to the following two conditions: (1) this
device may not cause harmful interference and (2) this device must accept any
interference received, including interference that may cause undesired operation.
LABEL OF THE END PRODUCT:
The final end product must be labeled in a visible area with the following " Contains
TX FCC ID: 2AJ9P-M905". If the size of the end product is larger than the palm of the
hand, then the following FCC part 15.19 statement has to also be available on the
label: This device complies with Part 15 of FCC rules. Operation is subject to the
following two conditions: (1) this device may not cause harmful interference and (2)
this device must accept any interference received, including interference that may
cause undesired operation.
