5. Antenna Information
5.1 Antenna Type
Antenna can be connected using On-board PCB antenna by default.
5.2 Reduce Antenna Interference
While using the On-board PCB antenna, in order to have the best Wi-Fi performance, it’s
recommended to keep a minimum15mm distance between the antenna part and the other metal
pieces.
User’s own PCBA design is recommended NOT to pass any wire, NOT do copper pour under
the region of the module’s antenna, to avoid interferences.


The storage for the delivered module should meet the following condition:
1. The anti-moisture bag should be kept in the environment with temperature< 30℃ and
humidity< 85% RH.
2. The expiration date is 6 months since the dry packaging products was sealed.
 Cautions:
1. All the operators should wear electrostatic ringin the whole process of production.
2. While operating, water and dirt should not have any contact with the modules.
