Interacto	A cape making BeagleBone interactive with a triple-axis accelerometer, gyroscope and magnetometer plus a 640 x 480/30 fps camera. All sensors are digital and communicate via I²C to the BeagleBone. The camera frames are captured using the PRU-ICSS. The sensors on this cape give hobbyists and students a starting point to easily build robots and flying drones.
