1 Description

The SiP module M904S is a small size module with conformal shielding.

The module provides full function of Bluetooth 4.0 Low Energy in a tiny

module via 48 pins LGA Foot Print. The M904S module provides

everything required to create Bluetooth 4.0 Low Energy product with RF,

baseband, MCU, qualified Bluetooth v4.0 stack and customer application

running on a single IC.

M904S 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 4.0 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.

10 SiP Module Preparations

10.1 Handling

Handling the module must wear the anti-static wrist strap to avoid ESD damage. After each module

is aligned and tested, it should be transport and storage with anti-static tray and packing. This

protective package must be remained in suitable environment until the module is assembled and

soldered onto the main board.

10.2 SMT Preparation

1. Calculated shelf life in sealed bag: 6 months at <40℃ and <90% relative humidity (RH).

2. Peak package body temperature: 250℃.

3. After bag was opened, devices that will be subjected to reflow solder or other high temperature

process must.

A. Mounted within: 72 hours of factory conditions <30℃/60% RH.

B. Stored at ≦10% RH with N2 flow box.

4. Devices require baking, before mounting, if:

A. Package bag does not keep in vacuumed while first time open.

B. Humidity Indicator Card is >10% when read at 23±5℃.

C. Expose at 3A condition over 8 hours or Expose at 3B condition over 24 hours.

5. If baking is required, devices may be baked for 12 hours at 125±5℃.

12 BQB/CE/FCC Certification

12.1 FCC (USA)

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.

Page 26

27

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-M904S". 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.

Professional installation

Section 15.204(b) states that an approved "transmission system" must always be marketed as a

complete system including the antenna.
