The VL53L0x ToF sensor measures the distance to the ground with high precision and the PMW3901 optical flow sensor measures movements of the ground. This creates a flying 3D robot that can be pre-programmed to fly distances in any direction or act as an aid for beginners as it creates a very stable flying platform. {{ :projects:crazyflie2:expansionboards:flow_deck_400px-1_grande.jpg?400 |}} ===== Specification ===== * [[http://www.st.com/en/imaging-and-photonics-solutions/vl53l0x.html|VL53L0x]] ToF sensor to measure distance up to 2 meters * {{ :projects:crazyflie2:expansionboards:pot0189-pmw3901mb-txqt-ds-r1.00-200317_20170331160807_public.pdf |PMW3901MB datasheet}} * 1-wire memory for automatic expansion deck detection * Designed for mounting under the Crazyflie 2.0 * Mechanical specification: * Weight: 1.6g * Size (WxHxD): 21x28x4mm ===== Schematic ===== {{ :projects:crazyflie2:expansionboards:flow-deck_reve.pdf | Flow deck RevE schematic }}
