5 Antenna Information
5.1 Antenna Type
By default, TYZS3 uses an onboard PCB antenna. You can also use an I-PEX connector

Tuya Inc. V2.0.0
to connect the module to an external antenna to extend the coverage in a complex
installation environment. If you use an I-PEX connector, the module BOM needs to be
changed. For the I-PEX connector version, contact Tuya business personnel.
5.2 Antenna Interference Reduction
To ensure optimal wireless performance when the Zigbee module uses an onboard PCB
antenna, it is recommended that the antenna be at least 15 mm away from other metal
parts and that the antenna location on the PCB be hollowed out.
To prevent adverse impact on the antenna radiation performance, avoid copper or traces
along the antenna area on the PCB. Ensure that there are no substrate media above or
below the antenna and that copper is at a certain distance away from the antenna to
maximize the antenna radiation performance, as shown in Figure 5-1.
Figure 5-1 Antenna placement
For details about the onboard PCB antenna area on TYZS3, see Figure 6-1.

6.3 Production Instructions
Storage conditions for a delivered module are as follows:
1. The moisture-proof bag is placed in an environment where the temperature is below
30°C and the relative humidity is lower than 70%.
2. The shelf life of a dry-packaged product is six months from the date when the product
is packaged and sealed.
Precautions:
1. Throughout the production process, each involved operator must wear an ESD wrist
strap and ESD suit.
2. During the operation, strictly protect the module from water and stains.

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.
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance 20
cm between the radiator and your body.
Radiation Exposure Statement:
This equipment complies with FCC 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.
