Abstract class for components in a DJI Product. A component can be a camera, gimbal, remote controller, etc. A DJI product consists of several components. All components of a product are subclasses of DJIBaseComponent and can be accessed directly from the product objects (DJIAircraft or DJIHandheld).
@property (nonatomic, assign, readonly) NSUInteger index
Returns the component index. Index is zero based. A component will have an index greater than zero when there are multiple components of the same type on the DJI product, and one of the components already has the index 0. For instance, M210 can have two gimbal mounted cameras, and will therefore have two gimbal components with indices 0 and 1, and two camera components with indices 0 and 1. For Matrice 600, there are printed numbers on the battery boxes. The DJIBattery component instance with index 0 corresponds to battery compartment number 1. For Inspire 2 and M200 series, DJIBattery with index 0 corresponds to the battery on the port (left hand) side of the aircraft. For M210 and M210 RTK, DJICamera and DJIGimbal with index 0 corresponds to the camera and gimbal on the port (left hand) side of the aircraft.
