Overview

The LR900-A/F Telemetry Radio is a small, cheap radio with superior performance for flight controller that typically allows ranges of better than 30kilometers. And it is very suitable for Pixhawk or other Audupilot/PX4 flight controller. It will connect automatically when power up without any configuration unless you need to implement some special features.

The LR900-A/F works in the 915MHz, so is better to use 2.4GHz receiver than 915MHz receiver (BlackSheep/ELRS 915) on your drones.
