Shenzhen Sctech Technology SC-33R01B Wireless Module
Product Description
The SC-33R01B module is a solution based on the ultra-low energy Bluetooth application system chip BK3633. The chip is designed with an advanced process and integrates a switching DCDC regulator with ultra-low power consumption. Embedded high interference suppression filter and fast automatic gain control logic make it work well in high interference environment. The BK3633 chip is a highly integrated wireless chip system that supports Bluetooth 5.2 dual mode and proprietary 2.4GHz protocol. It integrates high-performance RF transceivers, baseband, lowpower processors, feature-rich peripheral units, programmable protocols and configurations files to support a wide range of applications. Flash program memory makes it suitable for custom applications.

FCC Statement
This device complies with part 15 of the FCC rules. Operation is subject to
the following two conditions: (1) thi s device may not cause harmful
interference, and (2) this device must accept any interference received, incl
uding interference that may cause undesired operation. 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, pursuant to part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful inte
rference 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 important announcement
Important Note:
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 and your body. This transmitter
must not be co-located or operating in conjunction with any other antenna or
transmitter. Country Code selection feature to be disabled for products
marketed to the US/Canada. This device is intended only for OEM integrators
under the following conditions:
1. The antenna must be installed such that 20 cm is maintained between the
antenna and users ,and
2. The transmitter module may not be co-located with any other transmitter or
antenna,
As long as the three conditions above are met, further transmitter testing
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.
Important Note: In the event that these conditions cannot 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 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.
End Product Labeling
The final end product must be labeled in a visible area with the following”
Contains FCC ID: 2A4NI-33R01B”
Manual Information to the End User
The OEM integrator has to be aware not to provide information to the end user
regarding how to install or remove this RF module in the user’s manual of the
end product which integrates this module. The end user manual shall include
all required regulatory information/warning as show in this manual.
Integration instructions for host product manufacturers according to KDB
