The Bitcraze Flow Deck enhances the capabilities of the Crazyflie 2.X by enabling it to detect motion in any direction. It is equipped with a VL53L1x ToF sensor that precisely measures the distance to the ground, while the PMW3901 optical flow sensor detects ground movements. This combination allows the creation of a flying 3D robot that can be pre-programmed to navigate distances in any direction. Additionally, it serves as an aid for beginners by providing a stable flying platform, facilitating easier control and maneuverability.
