Herelink 2.4GHz Long Range HD Video Transmission System Hex Technology

From Hex and ProfiCNC, the team who brought you Pixhawk and The Cube GPS system, comes an all-in-one solution for long-range HD video transmission. The Herelink HD Digital Video Transmission System.

This 2.4GHz radio controller with built-in screen allows users to get long range HD video, telemetry, and control link up to a whopping 20km. It uses the 2.4GHz band on LTE over WIFI. This allows maximum transmission distance. Purported to have a range of 20km in FCC and 12km in CE.

The large 5.5″ screen displays a multitude of control options such as live images, autopilot configuration through the native QGround control or other GCS applications based on the Mavlink system.

The Air Unit uses between 5-12v input power and has a single UART for connection to the flight controller or other Mavlink accessories. Both the Air Unit and the Radio Controller are equipped with powerful Pinecone S1 processors with 4 cores at 2.2GHz and 4 more additional cores at 1.4GHz. This allows for tons of possibilities for app usage and future development.
