Herelink Overview

Herelink is an integrated remote controller, ground station and wireless digital transmission system designed to be used with the Cube Autopilot, Ardupilot or PX4. Herelink allows RC control, HD video and telemetry data to be transmitted upto 20km between the ground station and air unit, the Herelink remote controller features custom Solex TX and QGC applications and both air unit and ground station feature an integrated 8 core SOC for custom application development.
Herelink 1.1 is based on the original platform and functions of Herelink 1.0. The controller improved the display brightness up to 1000 nit. Moreover, an additional Ethernet interface is available on airunit1.1 to support more peripheral devices and adapt to more applications, a SD card slot is available on the airunit 1.1.
Note: Please use the latest version of flasher_win to upgrade your HereLink1.1 controller and HereLink1.1 airunit firmware. (https://docs.cubepilot.org/user-guides/herelink/herelink-user-guides/upgrading-firmware#download-firmware-upgrade-application)
