5.Antenna Signal

Antenna Type

Antenna can be connected only using On-board PCB antenna.

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 minimum 15mm 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.

Production Guide

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 ring in the whole process of production.
2. While operating, water and dirt should not have any contact with the modules.
