3. Mounting our board on the host PCBA
We suggest that you mounting our RF board(Holyiot-18010_nRF52840) on the board , something like that .
1 . for the best Bluetooth performance , the antenna of the area need to extends about several mml without ground under the
antenna of the edge of the host PCB
2 . the next choise is that place our board at the corner of host PCB , the antenna of board need to extends several mm
outside of the Ground plane of the host PCB

4. Miscellaneous
Soldering Temperature-Time Profile for Re-Flow Soldering
Maximum number of cycles for re-flow is 2. No opposite side re-flow is allowed due to module weight.

5. Absolute maximum ratings
Maximum ratings are the extreme limits to which the chip can be exposed for a limited amount of time
without permanently damaging it. Exposure to absolute maximum ratings for prolonged periods of time may
affect the reliability of the device.

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: 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.

Warning: Changes or modifications to this unit not expressly approved by the part
responsible for compliance could void the user's authority to operate the equipment.
FCC Radiation Exposure Statement
This equipment complied 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 only and the OEM integrators and instructed to
ensure that the end user has no manual instructions to remove or install the device. The OEM
integrator is still responsible for the FCC compliance requirement of the end product, which
integrates this module.
Integration is typically strictly restricted to Grantee himself or dedicated OEM integrators under
control of the Grantee.
In the event that these conditions can not be met (for example certain laptop configurations or
co-location with another transmitter. then the FCC authorization is no longer considered valid
and the FCC ID can not 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.
The module will be responsible to satisfy SAR/RF Exposure requirements, when the module
integrated into any (portable, mobile, fixed) host device.
The module must in the end-product be installed in such manner that the authorized antennas
can be used, any change of the antenna will void the certification.
LABEL OF THE END PRODUCT:
The final end product must be labelled in a visible area with the following "Contains TX FCC ID:
is smaller than 8x10cm, then additional FCC
part 15.19 statement is required to be available in the users manual: 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.
