# Holybro SiK Telemetry Radio - Long Range
|
|
|
|
This Holybro SiK Long Range Telemetry Radio is a small, light, and inexpensive open-source radio platform with an extended range (~20km) compared to the standard model.
|
|
|
|
This radio is plug-and-play, ready for all Pixhawk Standard and other similar flight controllers, providing the easiest way to set up a telemetry connection between your controller and a ground station.
|
|
It uses open-source firmware that has been specially designed to work well with MAVLink packets and to be integrated with PX4, ArduPilot, Mission Planner and QGroundControl.
|
|
|
|
The radios are available in 915 MHz or 433 MHz versions.
|
|
Please purchase the model that is appropriate for your country/region.

|
## Connecting to Flight Controller
|
|
|
|
Supply the power (7~28V) to the radio via the XT30 connector.
|
|
Use the 6-pin JST-GH connector that comes with the radio to connect the radio to your flight controller's `TELEM1` port.
|
|
|
|
Note that `TELEM2` can also be used, but you may need to [configure the telemetry port](../peripherals/mavlink_peripherals.md) on some flight controllers.
|
|
|
|
## Connecting to a PC or Ground Station
|
|
|
|
First, power the module with a 7~28V DC source.
|
|
Then, connect the radio to your Windows PC or Ground Station using a Type-C USB cable.
|
|
|
|
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 include the newly added COM port.
