Electrical Schematic

PCB Layout

Module antenna area couldn’t have GND plane or metal cross line, couldn’t place components nearby. It is better to make hollow out or clearance treatment or place it on the edge of PCB board.

Layout notes

The preferred Module antenna area is completely clear and not be prevented by metals, otherwise, it will influence the antenna’s effect (as above DWG. indication).
Cover the external part of the module antenna area with copper as far as possible to reduce the main board’s signal cable and other disturbances.
It is preferred to have a clearance area of 4 square meters or more area around the module antenna (including the shell) to reduce the influence to the antenna.
The device should be grounded well to reduce the parasitic inductance.
Do not cover copper under the module’s antenna to avoid affecting signal radiation or leading to transmission distance.
The antenna should be kept far from other circuits to prevent radiation efficiency reduction or affect the normal operation of other lines.
The module should be placed on the edge of the circuit board and keep a distance away from other circuits.
Suggesting to use of magnetic beads to insulate the module’s access power supply.

Certification

CE Certification
MS88SFA module is being tested and is expected to be compliant with the EU- Radio Equipment standards. OEM integrators should consult with a qualified test house to verify all regulatory requirements have been met for their complete device.

FCC Certification
Integration instructions for host product manufacturers according to KDB 996369 D03 OEM Manual v01

List of applicable FCC rules

The MS88SFA is a BT Module with GFSK modulation. It operates on the 2402MHz~2480MHz band and, therefore, is within U.S. FCC part 15.247 standard 2.3 Specific operational use conditions
The EUT is a BT Module

BLE:

Operation Frequency: 2402-2480MHz for BLE;
Modulation Type: GFSK
Number Of Channels: 40 channels
Antenna Designation: External Antenna
Antenna Gain: 3.29dBi

Limited module procedures
not applicable; Single Modular Approval Request

Trace antenna designs
Not applicable;

RF exposure considerations
The device has been evaluated to meet general RF exposure requirements. The device can be used in portable exposure conditions without restriction

Antennas
The MS88SFA is a BT Module that beams signals and communicates with its antenna, which is an External Antenna. The External Antenna gain is 3.29dBi. The antenna could not be in a no-load state when the module is working. During debugging, it is suggested to add 50 ohms load to the antenna port to avoid damage or performance degradation of the module under long-time no-load conditions.

Label and compliance information
The end product must be labeled in a visible area with the following
The host must Contain FCC ID: 2ABU6-MS88SFA. If the size of the end product is larger than 24x16mm, then the following FCC part 15.19 statement has to be available on the label: This device complies with Part 15 of FCC rules. Operation is subject to the following two conditions:

this device may not cause harmful interference and
this device must accept any interference received, including interference that may cause undesired operation.

Information on test modes and additional testing requirements
The data transfer module demo board can control the EUT work in RF test mode at a specified test channel.

FCC

Additional testing, Part 15 Subpart B disclaimer

The module is without an unintentional radiator digital circuit, so the module does not require an evaluation by FCC Part 15 Subpart B. The host should be evaluated by the FCC Subpart B.

ATTENTION
This device is intended only for OEM integrators under the following conditions:

The antenna must be installed such that 5 mm is maintained between the antenna and users, and
This device and its antenna(s) must not be co‐located with any other transmitters except following FCC multi‐transmitter product procedures. Referring to the multi-transmitter policy, multiple transmitter(s) and module(s) can be operated simultaneously without C2P.
For all products market in the US, OEM has to limit the Operating Frequency: to 2402-2480MHz by supplying a firmware programming tool. OEM shall not supply any tool or info to the end‐user regarding to Regulatory Domain change.

USERS MANUAL OF THE END PRODUCT
In the user manual of the end product, the end-user has to be informed to keep at least 5mm 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 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 8x10cm, then an additional FCC part 15.19 statement is required to be available in the user’s manual: This device complies with Part 15 of FCC rules. Operation is subject to the following two conditions:

this device may not cause harmful interference and
this device must accept any interference received, including interference that may cause undesired operation.

FCC STATEMENT

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, under 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 by 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 the receiver.
Connect the equipment to 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.

OEM integration instructions:

This device is intended only for OEM integrators under the following conditions:

The transmitter module may not be co-located with any other transmitter or antenna. The module shall be only used with the external antenna(s) that has been originally tested and certified with this module.
As long as the conditions above are met, further transmitter tests will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.).

Validity of using the module certification:

If these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization for this module in combination with the host equipment is no longer considered valid and the FCC ID of the module cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.

Reflow and Soldering

Do SMT according to the above reflow oven temperature deal curve. Max. Temperature Refer to IPC/JEDEC standard; Peak TEMP<260℃； Times：≤2 times， suggest only do once reflow soldering on module surface in case of SMT double pad involved. Contact us if special crafts are involved.
Suggesting to make 0.2mm thickness of module SMT for partial ladder steel mesh, then make the opening extend 0.8mm
After unsealing, it cannot be used up at one time, should be vacuumed for storage, and shouldn’t be exposed to the air for a long time. Please avoid getting damp and soldering-pan oxidizing. If there are 7 to 30 days intervals before using online SMT, suggest to bake at 65-70 ℃ for 24 hours without disassembling the tape.
Before using SMT, please adopt ESD protection measures.
