BM-52840

Description

BM-52840 is a Bluetooth 5 Low Energy

class 1 module that provides a complete

solution from various interfaces to different

sensors to BLE protocol stack and applica-

tions. It includes 32MHz crystal and a sys-

tem-on-chip Nordic nRF52840. The mini-

mal parts count and small footprint of the

BM-52840 is ideally suited for the re-

quirement of high integration Bluetooth

Low Energy technology in portable devices

and consumer electronics.

The system-on-chip architecture design of

the module makes a much smaller space

and minimal cost and simplifies the whole

system design.

Placement Guideline

It is recommended that BM-52840 be placed on the corner of the main board or
near the edge as shown below.

On the corner

Near the edge

However, placing BM-52840 inside the main board affects the RF performance and
may reduce the RF range significantly.

FCC Warning

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.

NOTE: Any changes or modifications to this unit not expressly approved by the party responsible for compliance

could void the user's authority to operate the equipment.

FCC Radiation Exposure Statement:

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End

users must follow the specific operating instructions for satisfying RF exposure compliance.This transmitter must

not be co-located or operating in conjunction with any other antenna or transmitter.

Note 1: Compliance of this device in all final host configurations is the responsibility of the Grantee.

OEM integrators are responsible to satisfy RF exposure requirements. SAR evaluation is valid for portable,

mobile and fixed applications.

Note 2: Any modifications made to the module will void the Grant of Certification, this module is limited to OEM

installation only and must not be sold to end-users, end-user has no manual instructions to remove or install the

device, only software or operating procedure shall be placed in the end-user operating manual of final products.

Note 3: The device must not transmit simultaneously with any other antenna or transmitter.

Note 4: To ensure compliance with all non-transmitter functions the host manufacturer is responsible for ensuring

compliance with the module(s) installed and fully operational. For example, if a host was previously authorized as

an unintentional radiator under the Declaration of Conformity procedure without a transmitter certified module

and a module is added, the host manufacturer is responsible for ensuring that the after the module is installed and

operational the host continues to be compliant with the Part 15B unintentional radiator requirements. Since this

may depend on the details of how the module is integrated with the host, CC&C Technologies, Inc. shall provide

guidance to the host manufacturer for compliance with the Part 15B requirements.

Note 5: FCC ID label on the final system must be labeled with “Contains FCC ID: PANBM52840”

The transmitter module must be installed and used in strict accordance with the manufacturer's instructions as

described in the user documentation that comes with the host product. CC&C Technologies, Inc. is responsible for

the compliance of the module in all final hosts.
