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.
