# Hardware (Drones\&Parts)

This section contains information about complete pre-built PX4 vehicles, and components that you can use if building your own drones:

* [Complete Vehicles](https://px4.gitbook.io/px4-user-guide/drone_parts/complete_vehicles) - Complete Ready to Fly (RTF) or near-RTF vehicles (i.e. may require battery, RC controller)
* [Flight Controllers (Autopilots)](https://px4.gitbook.io/px4-user-guide/drone_parts/flight_controller) - Autopilot hardware options (including [Pixhawk Series](https://px4.gitbook.io/px4-user-guide/drone_parts/flight_controller/pixhawk_series))
* [Flight Controller Peripherals](https://px4.gitbook.io/px4-user-guide/drone_parts/peripherals) - Components that can be attached to the flight controller (GPS, compass, motors, rangefinders, etc.). The device pages also explain how to configure the components to work with PX4.
* [Companion Computers](https://px4.gitbook.io/px4-user-guide/drone_parts/companion_computer) - Separate "mission computers" that enable advanced flight control features such as [Computer Vision](https://px4.gitbook.io/px4-user-guide/drone_parts/companion_computer/computer_vision) (and their [peripherals](https://px4.gitbook.io/px4-user-guide/drone_parts/companion_computer/companion_computer_peripherals)).
