Antenna Information
Antenna Type
The antenna can be connected using an on-board PCB antenna or an external antenna; the default way is using the on-board PCB antenna. If an external antenna is needed, please contact the BD manager.
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.

Note: the tolerance of the PCB outline border is ±0.15mm, and the tolerance of PCB thickness is ±0.1mm
Production Guide
The storage for the delivered module should meet the following condition:
- The anti-moisture bag should be kept in an environment with a temperature < 30℃ and humidity < 85% RH.
- The expiration date is 6 months since the dry packaging products were sealed.
Cautions:
- All the operators should wear an electrostatic ring in the whole process of production.
- While operating, water and dirt should not contact the modules.
