 Clover is an open source [ROS](https://www.ros.org)-based framework, providing user-friendly tools to control [PX4](https://px4.io)-powered drones. Clover is available as a ROS package, but is shipped mainly as a preconfigured image for Raspberry Pi. Once you've installed Raspberry Pi on your drone and flashed the image to its microSD card, taking the drone up in the air is a matter of minutes.
