100mW Holybro Telemetry Radio Set V3 (433Mhz)

The Holybro Telemetry Radio Kit allows you to easily add a two-way telemetry connection between your autopilot and ground station wirelessly, providing unparalleled ease of use for viewing in-flight data, changing missions on the fly, and tuning. The 100mW version typically allows ranges of better than 300m “out of the box”, but can be extended to several kilometres with the use of a patch antenna on the ground. The radio uses open source firmware that has been specially designed to work well with MAVLink packets. The modules also feature a bootloader that permits radio firmware upgrades over the serial interface.

The radios at interchangeable between the air and ground modules and the set comes with cables to connect with the Pixhawk 4 Flight Controller and an OTG cable for connection with a tablet.

We sell 433Mhz / 915Mhz versions: 433Mhz is for the UK and most of Europe. 915Mhz for USA, Canada, Australia & New Zealand - please select as appropriate for your region.

Connecting to a PC:
Connecting the radio to your Windows PC is as simple as connecting the micro USB cable to your PC. The necessary drivers should be installed automatically and the radio will appear as a new “USB Serial Port” in the Windows Device Manager under Ports (COM & LPT). The Mission Planner’s COM Port selection drop-down should also contain the same new COM port.
