The Light Pro beacon is to be integrated inside the drone and it must be powered by a voltage source of 5V to 8.4V. An LED indicates its status. Its featherweight of only 23 g allows the device to be integrated into very small aircraft. Its low consumption of 40 mA on average does not penalize the autonomy of the drone. The external antenna provides a range of 3 km in optimal situations and facilitates integrations where the antenna needs to be deported outside the drone chassis. It has a web interface that allows you to check the operation of the beacon and display other nearby beacons in reception mode.
