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.

Top side
Top side
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.
