Start here

Let’s get started!

If you just bought a Crazyflie 2.X a good way to start is to head over to the Getting started with the Crazyflie 2.X guide to see how to assemble the kit and take off for your first flight. If you want to add one of our many expansion decks to the Crazyflie 2.X and need help getting started we have made a Getting started with expansion decks tutorial. Just follow the steps and you are ready to go.

Just bought our Loco positioning system? Go to our Loco Positioning system page for more information and how to setup the system.

We have collected all getting started guides in the Tutorials menu, this is the place to look for instructions.


When you are comfortable flying the Crazyflie you might feel that it is time for the next step, to make use of the flexibility of the platform. After all it is designed to be modified! Check out the Getting started with development tutorial to setup your development environment, build your first custom firmware and download it to the copter.

Maybe you want to add a sensor or some other hardware? Heat up your soldering iron and dive into it! Find more information about the expansion bus. The documentation is the place to look for documentation related to products and projects.

All the source code is hosted on and this is also where you will find documentation related to each repository.


Looking for inspiration for a new project? Take a look at our blog posts. The Video gallery contains some really cool stuff as well as our You Tube channel. We also have a list of academic groups that have used the Crazyflie in their research.


Open source is about sharing, creating something awesome together and contribute to the greater good! It is easy, fun and anyone can do it, read more about how to contribute.
