By default, ZN5 uses an onboard PCB antenna.
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:
Make sure that there is no substrate medium directly below or above the printed antenna.
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.
The PCB dimensions (H x L x W) are 0.8±0.1 mm x 20.4±0.35 mm x 14.8±0.35 mm.
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.
Set oven temperatures according to the following temperature curve of reflow soldering. The peak temperature is 245°C.

Radiation Exposure Statement
This device complies with FCC radiation exposure limits set forth for an uncontrolled rolled environment. This device should be installed and operated with a minimum distance of 20cm between the radiator and your body.
Important Note
This radio module must not be installed to co-locate and operating simultaneously with other radios in the host system except following FCC multi-transmitter product procedures. Additional testing and device authorization may be required to operate simultaneously with other radios.
The availability of some specific channels and/or operational frequency bands are country dependent and are firmware programmed at the factory to match the intended destination. The firmware setting is not accessible by the end-user.
The host product manufacturer is responsible for compliance with any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. The final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.
The end-user manual shall include all required regulatory information/warnings as shown in this manual, including “This product must be installed and operated with a minimum distance of 20 cm between the radiator and user body”.
This device has got an FCC ID: 2ANDL-ZN5. The end product must be labelled in a visible area with the following: “Contains Transmitter Module FCC ID: 2ANDL-ZN5”.
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.
