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 or SkyPort, developers can apply high power,status information and other resource from DJI's drone.
Developers can use PSDK to develop payload within the scope allowed by DJI. The copyright of payload developed based on DJI PSDK belongs to the developer. DJI will not request the developer's code in any form or reason. If you need to use DJI PSDK to develop payload devices, please register a PSDK Enterprise Account; if you need to develop more than 9 payloads, please apply for mass production permission.
