JZ Drones PT4 Four Drop Kit: Lightweight Four-Stage Payload Release System for Controlled Multi-Drop Operations
The JZ Drones PT4 Four Drop Kit is a DJI PSDK-based aerial payload delivery system designed for controlled, multi-point deployment using DJI Matrice platforms, including the Matrice 300 RTK, Matrice 350 RTK, and Matrice 400. It mounts via the DJI SkyPort V2 interface and integrates directly with DJI Pilot 2, allowing operators to monitor payload status and trigger releases in real time.
The system supports up to four payloads with independent or simultaneous release, making it suitable for search and rescue, emergency logistics, and industrial operations. With a lightweight 120 g design, laser-assisted targeting, and no external power requirement, it enables efficient and repeatable aerial delivery missions.
