WBR3S uses only an onboard PCB antenna.
5.2
Antenna Interference Reduction
To ensure optimal WiFi performance when the WiFi module uses an onboard PCB
antenna, it is recommended that the antenna be at least 15 mm away from other
metal parts. To ensure the antenna performance, the PCB should not be routed
or clad with copper in the antenna area. The main points of the layout: 1. Make
sure that there is no substrate medium directly below or above the printed antenna.
2. Make sure that the area around the printed antenna is far away from the metal
copper skin, so as to ensure the radiation effect of the antenna to the greatest
extent

Production Instructions
1.
Use an SMT placement machine to mount the stamp hole module that Tuya
produces onto the PCB within 24 hours after the module is unpacked and the
fifirmware is burned.If not, vacuum pack the module again. Bake the module
before mounting it onto the PCB. A. SMT placement equipment
