It can be used for a number of things but the primary usage is as a development platform and for quadcopter enthusiasts that would like a nano-quad. Here's a list of some possible uses:
Here's a short list of what is needed for flying:
The Crazyflie is controlled from a computer using an input device such as a gamepad. A radio dongle is used to send control data to the quadcopter.
The Crazyflie has 4 different controls: Pitch, roll, yaw and thrust. Changing the pitch and roll will make the quadcopter tilt to the sides and thus change the direction that it's moving in. Tiling the quadcopter forward will make it go forward and the same applies for every other direction.

Changing the yaw will make the quadcopter spin. Changing the yaw is normally not a good idea since this will also change what direction is forward for the quadcopter.

The thrust is used to control the altitude of the quadcopter.
The frequency used communication is based on 2.4 GHz. For every quadcopter it's possible to set a channel between 0-128 (?) that will be used for communication. This means that once the channels is set for a quadcopter you will have to specify the appropriate channel when communicating with it.
The Crazyflie is contructed without a separate frame, it uses the PCB as a frame and simply attaches four motors to it. This means that the weight of the platform is very low and on most impacts it simply bounces of objects. If you are unlucky either propellers or motors might break when crashing. If so have a look at our troubleshooting page for some basic troubleshooting and repairs.
For more tips on flying take a look at the tips and tricks page.
Below are the basic components mapped out on the Crazyflie.
The Crazyflie has four LEDs mounted, two blue, one red and one green. The two blue LEDs indicate that the system is powered and the red/green shows operation.
