The multi-ranger deck gives the Crazyflie 2.X the ability to detect objects around it. This is done by measuring the distance to objects in the following 5 directions: front/back/left/right/up with mm precision up to 4 meters.
To get the most out of your Multi-ranger it should be paired with a Flow deck, which will measure the movement along the ground and the distance to the ground.
