Mechanical Dimensions
See Figure 2 below for details, which is the mechanical dimension diagram of the module.
Packaged
See Figure 3 below for details, and schematic encapsulation is recommended.
See Figure 4 below for details, recommended PCB package size drawing.
Installation
In order to ensure the radiation effect of the antenna to the greatest extent, it is recommended that:
- The three-dimensional distance between the antenna area of the module and the metal parts of the user’s products (such as shell positioning screws, power wires, signal wires, hardware, etc.) should be at least 6~15mm;
- The user’s PCB board should be directly below the module antenna area and in the surrounding 6mm area, and the PCB should not be traced or copper poured;
- The module is located in one corner or one side of the product, and the antenna area is external and to the user.
As shown in Figure 5 and Figure 6, Figure 5 is preferred.
Reference Design
The external reference circuit of the TRZB1 module is shown in Figure 7 below.

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.
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 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 important announcement
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.
The availability of some specific channels and/or operational frequency bands is country-dependent and
firmware programmed at the factory to match the intended destination.
The firmware setting is not accessible by the end-user.
Contains Transmitter Module: 2BAGQ-TRZB1
This radio module must not be installed to co-locate and operating simultaneously with other radios in the host system, additional testing and equipment authorization may be required to operate simultaneously with other radios.
The final end product must be labeled in a visible area with the following:
