By default, TYZS4 uses the PCB onboard antenna.
To optimize the Zigbee performance of the wireless module in combination with the PCB onboard antenna, it is recommended to keep the antenna at least 15mm from other metal parts. It is recommended that the corresponding antenna area of the adapter board be hollowed out for the best effect.
The user PCB board should not be routed around the antenna area and should not be covered with copper to avoid affecting the antenna radiation performance.
When packaging, customers can directly reference the above plug-in content and the packaging file in Altium Designer format.
The moisture-proof bag must be placed in an environment where the temperature is below 40°C and the relative humidity is lower than 90%.
The shelf life of a dry-packaged product is 12 months from the date when the product is packaged and sealed.
There is a humidity indicator card (HIC) in the packaging bag.
Perform mounting with the SMT based on the following reﬂow oven temperature curve. The highest temperature is 245°C. The reflow temperature curve is as below:
A: Temperature axis
B: Time axis
C: Liquidus temperature: 217 to 220°C
D: Ramp-up slope: 1 to 3°C/s
E: Duration of constant temperature: 60 to 120s; the range of constant temperature: 150 to 200°C
F: Duration above the liquidus: 50 to 70s
G: Peak temperature: 235 to 245°C
H: Ramp-down slope: 1 to 4°C/s
Note: The above curve is just an example of the solder paste SAC305. For more details about other solder pastes, please refer to Recommended oven temperature curve in the solder paste specifications.

This device has got an FCC ID: 2ANDL-TYZS4. The end product must be labeled in a visible area with the following: “Contains Transmitter Module FCC ID: 2ANDL-TYZS4”.
This device is intended only for OEM integrators under the following conditions:
The antenna must be installed such that 20cm is maintained between the antenna and users, and the transmitter module may not be co-located with any other transmitter or antenna.
As long as the 2 conditions above are met, further transmitter tests 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.
