Interfaces
This page describes the general information and interfaces location of AIRLink Telemetry Module.
Front side
Pin number | Pin name | Direction | Voltage level | Function |
|---|---|---|---|---|
1 | 5V | OUT | +5V | Radio module power supply |
2 | 5V | OUT | +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.

RSSI LEDs status:
- Blinking in turn: searching for pair
- Blinking all at once: RF disabled
- Solid: RF connection established, pair found
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.
Bottom side
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.
