ETHERNET - JST GH SM08B-GHS-TB

Pin number	Pin name	Direction	Voltage level	Function
1	5V	IN	+5V	Radio module power supply
2	5V	IN	+5V	Radio module power supply
3	ETH_TXP	OUT	+3.3V	Ethernet transmit positive
4	ETH_TXN	OUT	+3.3V	Ethernet transmit negative
5	ETH_RXP	IN	+3.3V	Ethernet receive positive
6	ETH_RXN	IN	+3.3V	Ethernet receive negative
7	GND			Ground
8	GND			Ground

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.

FAN - JST GH SM06B-GHS-TB

Pin number	Pin name	Direction	Voltage level	Function
1	5V	OUT	+5V	Fan output
2	Reserved
3	Reserved

RSSI LEDs status:

• Blinking in turn: searching for pair

• Blinking all at once: RF disabled

• Solid: RF connection established, pair found

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.
