# Loading Firmware
_QGroundControl_ **desktop** versions can install [PX4 Pro](http://px4.io/) or [ArduPilot](http://ardupilot.com) firmware onto Pixhawk-family flight-controller boards. By default QGC will install the current stable version of the selected autopilot, but you can also choose to install beta builds, daily builds, or custom firmware files.
_QGroundControl_ can also install the firmware for SiK Radios and PX4 Flow devices.
> **Caution** Loading Firmware is currently not available on tablet or phone versions of _QGroundControl_.
## Connect Device for Firmware Update
> **Caution** **Before you start installing Firmware** all USB connections to your vehicle must be _disconnected_ (both direct or through a telemetry radio). The vehicle must _not be_ powered by a battery.
1. First select the **Gear** icon (_Vehicle Setup_) in the top toolbar and then **Firmware** in the sidebar.

1. Connect your device (Pixhawk, SiK Radio, PX4 Flow) directly to your computer via USB.
::: info
Connect directly to a powered USB port on your machine (do not connect through a USB hub).

## Select Firmware to Load
Once the device is connected you can choose which firmware to load (_QGroundControl_ presents sensible options based on the connected hardware).
1. For a Pixhawk-compatible board choose either **PX4 Flight Stack vX.X.X Stable Release** or **ArduPilot Flight Stack** radio buttons to download the _current stable release_.

If you select _ArduPilot_ you will also have to choose the specific firmware and the type of vehicle (as shown below).
![Select ArduPilot](../../../assets/setup/firmware/firmware_selection_ardupilot.jpg)
1. Check **Advanced settings** to select specific developer releases or install firmware from your local file system.

## Update the firmware
1. Click the **OK** button to start the update.
The firmware will then proceed through a number of upgrade steps (downloading new firmware, erasing old firmware etc.).
Each step is printed to the screen and overall progress is displayed on a progress bar.

Once the firmware has finished loading the device/vehicle will reboot and reconnect.
Next you will need to configure the [airframe](../setup_view/airframe.md) (and then sensors, radio, etc.)
