The Payload Software Development Kit 2.0 (PSDK 2.0) is a developer kit comprising the hardware adapter and reference materials required to build custom payloads for compatible DJI enterprise platforms. PSDK enables developers to access the aircraft's flight controller, gimbal control, video transmission, and power systems, building specialised payloads such as searchlights, megaphones, environmental sensors, mapping cameras, or computer vision modules. Used in combination with the Skyport, X-Port, or E-Port hardware interface depending on the target airframe. Refer to developer.dji.com for the latest PSDK version (currently v3.x) and full technical documentation.
