Holybro 433Mhz 915Mhz 500mW Transceiver Radio Telemetry Set V3 for PIXHawk 4 Flight Controller
It is a small, light and inexpensive open source radio platform that typically allows ranges of better than 300m “out of the box”
(the range can be extended to several kilometers with the use of a patch antenna on the ground).
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.

– 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 4 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.
