The Matrice 300 Series Upward Gimbal Connector (PART11) mounts to the top of the Matrice 300 RTK or Matrice 350 RTK and accepts a single compatible payload — typically used to add an upward-facing camera or sensor for under-bridge inspection, ceiling/eaves surveys, or other below-or-above structure work. Compatible with the Zenmuse H20, H20T, Z30, and other official DJI PSDK payloads (XT2 not supported on upward mount). Adds IP44 protection when used with appropriately rated payloads.
