# SiK Radio
|
|
|
|
[SiK radio](https://github.com/LorenzMeier/SiK) is a collection of firmware and tools for telemetry radios.
|
|
|
|
PX4 is protocol-compatible with radios that use _SiK_.
|
|
SiK Radios often come with appropriate connectors/cables allowing them to be directly connected to [Pixhawk Series](../flight_controller/pixhawk_series.md) controllers
|
|
(in some cases you may need to obtain an appropriate cable/connector).
|
|
Typically you will need a pair of devices - one for the vehicle and one for the ground station.
|
|
|
|
Hardware for the SiK radio can be obtained from various manufacturers/stores in variants that support different range and form factors.
|
|
|
|
|

|
|
|
|
## Setup/Configuration
|
|
|
|
The ground station-based radio is connected via USB (essentially plug-n-play).
|
|
|
|
The vehicle-based radio is connected to the flight-controller's `TELEM1` port, and typically requires no further configuration.
|
|
|
|
## Firmware Update
|
|
|
|
Hardware sourced from most [vendors](#vendors) should come pre-configured with the latest firmware.
|
|
You may need to update older hardware with new firmware, for example to gain support for MAVLink 2.
|
|
|
|
You can update the radio firmware using _QGroundControl_: [QGroundControl User Guide > Loading Firmware](https://docs.qgroundcontrol.com/master/en/qgc-user-guide/setup_view/firmware.html).
|
|
|
|
## Advanced Setup/Configuration
|
|
|
|
The Development section has [additional information](../data_links/sik_radio.md) about building firmware and AT-command based configuration.
|
|
This should not be required by non-developers.
