About this product

The Herelink HD Digital Video Transmission System V1.1 is an all-in-one solution for long-range HD video transmission. Brought to you by Hex and ProfiCNC, the team who brought you Pixhawk and The Cube GPS system.

The Herelink Air Unit 1.1 Integrates a data link unit, remote control link, and video display unit into a single device, making a complex device system integrated and miniaturized. This VTX unit features a signal transmission range up to 20KM,  minimum latency of 110ms, two HDMI inputs, and supports 720p 30fps, 1080p 30fps / 60fps video format. The Air Unit uses between 5-12v input power and has a single UART for connection to the flight controller or other Mavlink accessories. Now updated with Sd Card Slot and Ethernet port. 

The Herelink Controller 1.1 is a  2.4GHz radio controller with a built-in screen that 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. 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. Now updated with a brighter screen at 1000 nit.


  • Controller Screen brightness updated to 10000 nit.
  • Ethernet port added to Air Unit
  • SD card slot added to Air Unit
