Overview
NRF52832AA(holyiot-17095) which we selected Nordic nRF52832 WL-CSP Chip(BGA
chip) ,the NRF52832AA is very very Tiny module , the size is just about 9.4mm*9.25mm ,
just like a finger size.
The NRF52832AA is a powerful, highly flexible ultra-low power multiprotocol SoC ideally
suited for Bluetooth low energy (previously called Bluetooth Smart),32-bit ARM ® cortex
TM -M4F ,
Which support Bluetooth 4.0 ,BLuetooth mesh . there are 11 GPIOs , we also layout the
SWDIO,SWCLK ,VCC and GND for the developer debug and program by themselves.

About Us
We are a company who located in shenzhen ,China . we have already develop a lot of IOT
products , such as smart jump rope , smart pets training, pets fitness and health
tracking ,key finder for anti-lost . Smart bluetooth tag , smart sexy product . We
cooperation with a lot of customers . Like south Korea , USA , Germany , Greece ,
Israel . We help our partner to work with the firmware code via BLE solutions . Help
them solve the distance range , and let the products more low energy and battery will
be last longer . We are focus on iBeacon ,eddystone , BLE bluetooth 4.0
with different sensor like temperature sensor , humidity sensor , pressure sensor , air
quality sensor , accelerometer sensor (motion ) such as 3-axis accekerometer 6-axis
accelerometer , 9- acceleromter sensor (Gyroscope) . Barometric pressure sensor .
And so on . We provide BLE solutions ,RF solutions for our customer . We can
customize different firmware for our client . We provide one- stop service . Like PCB
design ,PCBA layout ,PCBA produce, firmware and case design . And work with the app
developer to complete the whole solutions . From app, web applications to compatible
with our firmware .

FCC Statement:
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.
LABEL OF THE END PRODUCT:
The final end product must be labelled in a visible area with the following "Contains TX FCC
ID:" 2ALGYNRF52832AA " If the size of the end product 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.
RF Exposure
This device has been evaluated and shown compliant with the FCC RF Exposure limits under
fixed exposure conditions (antennas are greater than 20cm from a person's body) when
installed in certain specific OEM configurations.
This modular complies with FCC RF radiation exposure limits set forth for an uncontrolled
environment. This transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter. Due to missing shielding the module is strictly limited to integration by
the Grantee himself or his dedicated OEM integrator under control of the Grantee. However,
the OEM integrator is still responsible for testing their end-product for any additional
compliance requirements required with this module installed.

IMPORTANT NOTE:
This device is intended only for OEM integrators under the following conditions:
(1) According to FCC Part 15 Subpart C Section 15.212, the radio elements of the
modular transmitter must have their own shielding. However, due to there is no shielding
for this BT module, this module is granted as a Limited Modular Approval. This module
has been designed to operate with a internal antenna having a maximum gain of 2 dBi.
(2) 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.
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.
The module has no shielding and tested stand alone. This module is tested and approved as
Limited modular approval with stand alone configuration, any OEM incorporated this radio
module into any system are require additional testing and evaluation.
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.
