## What is the DJI Payload SDK?

The DJI Payload SDK(PSDK), is a development kit provided by DJI to support developers to develop payload that can be mounted 
on DJI drones. Combined with the X-Port, SkyPort or extension port adapter, developers can obtain the information or other 
resource from the drone. According to the software logic and algorithm framework designed by the developer, users could 
develop payload that can be mounted on DJI Drone, to perform actions they need, such as Automated Flight Controller, 
Payload Controller, Video Image Analysis Platform, Mapping Camera, Megaphone And Searchlight, etc.
