We are pleased to announce the release of a new expansion deck for Crazyflie 2.0: the Flow deck. The flow deck is a new expansion board for Crazyflie 2.0 that contains an optical flow sensor from Pixart and a ranging sensor. These two sensors allows the Crazyflie to understand how it is moving above the floor and using this information the Crazyflie can fly itself.
The Flow deck can be used for manual flight where it allows to super easily fly the Crazyflie: if you realease all joystick the Crazyflie just stays there and hovers! The flow deck is even more interesting when used in combination with scripting: it is now possible to script the Crazyflie movement to achieve autonomous flight without needing any external positioning system.
