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.

6.3 Production Guide

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.
