Telemetry Radio V3 433MHz
A Holybro Telemetry Radio is a small, light and inexpensive open source radio platform that typically allows ranges of better than 300m “out of the box”). The radio uses open source firmware which has been specially designed to work well with MAVLink packets and to be integrated with the Mission Planner, Copter, Rover and Plane.

•Status LEDs
The radios have 2 status LEDs, one red and one green. The meaning of the different LED states is:
Green LED blinking – searching for another radio
Green LED solid – link is established with another radio
Red LED flashing – transmitting data
Red LED solid – in firmware update mode
• Connecting to Pixhawk4
Use the 6 pin JST-GH connector that should have come with the radio to connect the radio to your Pixhawk4’s “Telem 1” (“Telem 2” can also be used but the default recommendation is “Telem1”).

• Connecting to a PC
Connecting the radio to your Windows PC is as simple as connecting the micro USB cable (which should have been included with the radio) 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.
