Antenna

Antenna type

Default copper column antenna connection.

At the same time, an external antenna can be connected via the Ipex connector for extended coverage in complex installation

Antenna interference reduction

To optimize the Zigbee performance of the wireless module in combination with the copper column antenna, it is recommended to keep the antenna at least 15mm from other metal parts. It is recommended that the corresponding antenna area of the adapter board be hollowed out for the best effect.

The user PCB board should not be routed around the antenna area and should not be covered with copper to avoid affecting the antenna radiation performance.

PCB recommended packaging

Production guide

The storage conditions for the module after it has been shipped are as follows:

1. The moisture-resistant bag must be stored at a temperature below 30℃, and under a relative humidity below 85%.
2. The shelf life of dry-packed products is six months following the packaged date.
