The ethernet interface is decoupled with capacitors. Ethernet cable should be twisted to reduce EMI noise. Shorter cables are recommended for increased performance and higher bandwidth of the interface.

RSSI LEDs status:
Blinking in turn: searching for pair
Blinking all at once: RF disabled
Solid: RF connection established, pair found
The top side has an enclosure-integrated heatsink.
AIRLink telemetry module is designed to work standalone (no cooling fan) without overheating at maximum output power with ambient temperatures of up to 50° C.
In case there is a chance of overheating in your application - the module has 4x M3 mounting holes for the cooling fan.
The top side has an a heatsink and mounting holes for an optional fan. It's important to have a clear space to allow for airflow circulation in front of this side.
