Features

2.13 Wireless

The Maury may be equipped with a AzureWave CM276NF WiFi and BT module. The antennas are connected directly to the module.

3. Specifications

3.1 Absolute Maximum Ratings

Absolute maximum ratings reflect conditions that the module may be exposed outside of the operating limits, without experiencing immediate functional failure. Functional operation is only expected during the conditions indicated under “Recommended Operating Conditions”. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the module. Exposure to absolute -maximum rated conditions for extended periods may affect device reliability.
