Mesh Networking Module CTL3212
1. General Description
The Module (CTL3212) is a fully-integrated, pre-certified module, enabling rapid development of
wireless mesh networking solutions.
Based on the Silicon Labs EFR32™ Mighty Gecko SoC, the CTL3212 combines an energyefficient, multi-protocol wireless SoC with a proven RF/antenna design and industry leading
wireless software stacks. This integration accelerates time-to-market and saves months of
engineering effort and development costs.
The size of CTL3212 is 22x13x2.6mm.It integrated a 2.4GHz, IEEE 802.15.4-2003 compliant
transceiver with a 32-bit network processor (ARM Cortex-M4 Processor) .It contains embedded
FLASH and integrated RAM for program and data storage.

12. PCB Layout Recommendations
Please reference Mechanical Dimensions shown in next section for PCB layout.
The area underneath the module should be covered with solder mask in order to prevent short
circuit on the test pads on the back side of the module. A solid ground plane under the module is
preferred.
As the module integrated with onboard PCB trace antenna, the mounting position of the module will
have great impact on the RF performance. There should not be any trace, ground plane or metal
part underneath or nearby the area of the onboard PCB trace antenna. The figure below shows an
example how the module positioned on the mother PCB.

15. Regulatory Statements
16.1 FCC Statements
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.
Cet appareil est conforme à la section 15 des réglementations de la FCC. Le fonctionnement de
l’appareil est sujetaux deux conditions suivantes :
1) cet appareil ne doit pas provoquer d’interférences néfastes, et
2) cet appareil doit tolérer les interférences reçues, y compris celles qui risquent de
provoquer un fonctionnement indésirable.
Note: This product 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 product 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 product 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 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.
Note 1: This module certified complies with RF exposure requirements under mobile or fixed
condition; this module is to be installed only in mobile or fixed applications.
A mobile device is defined as a transmitting device designed to be used in other than fixed locations
and to generally be used in such a way that a separation distance of at least 20 centimeters is
normally maintained between the transmitter's radiating structure(s) and the body of the user or
nearby persons. Transmitting devices designed to be used by consumers or workers that can be
easily re-located, such as wireless devices associated with a personal computer, are considered to
be mobile devices if they meet the 20 centimeter separation requirement.

Rev. 2
Mesh Networking Module CTL3212
A fixed device is defined as a device is physically secured at one location and is not able to be
easily moved to another location.
Note 2: Host product manufacturers must provide in their user manual the required RF exposure
information for mobile & fixed usage of this module. Host product manufacturers must use the
following RF exposure statement in their user manual “This equipment complies with FCC radiation
exposure limits set forth for an uncontrolled environment. This equipment should be installed and
operated with a minimum distance of 20 cm between the radiator and all persons. This transmitter
must not be co-location or operating in conjunction with any other antenna or transmitter.”
Note 3: 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 shall have 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 4: Additional testing and certification may be necessary when multiple modules are used.
Note 5: The module may be operated only with the integral chip antenna with which it is authorized.
Note 6: 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 Supplier’s 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, the manufacturer shall provide
guidance to the host manufacturer for compliance with the part 15B requirements.
Note 7: The FCC ID label on the final system must be labeled with “Contains FCC ID: 2AAUQ-
CTL3212” or
“Contains transmitter module FCC ID: 2AAUQ-CTL3212”.
Note 8: The FCC rule/s for this module are CFR 47 Part 15 Subpart C.
Note 9: This modular transmitter is only FCC authorized for the specific rule parts listed on its grant.
The host product manufacturer is responsible to any other FCC rules that apply to the host not
covered by the modular transmitter grant of certification. The final host product will require Part 15
Subpart B compliance when the modular transmitter is installed.
16.2 ISED Statements`
This device complies with Innovation, Science and Economic Development Canada’s
license-exempt RSS standard(s). Operation is subject to the following two conditions:
1) this device may not cause interference, and
