Efficient Heat Dissipation.\u003c\/b\u003e\nThe DJI O4 Pro image transmission module generates significant heat during high-power operation—thermal throttling degrades signal and can trigger mid-flight shutdowns. The DolphinRC heatsink kit replaces the stock plastic housing with a CNC-machined aluminum alloy shell that acts as a massive passive heatsink. Thermal energy conducts away from the electronics, through the aluminum, and into the airflow. Thermal grease pads included ensure maximum thermal transfer between the module and the heatsink surfaces.\n\n\u003cb\u003eFull-Wrap Cooling Armor. Top + Bottom Coverage.\n\u003c\/b\u003eThe kit includes both top and bottom aluminum covers—not just a single-sided heatsink. The module is fully encased in thermally conductive aluminum, maximizing surface area for heat dissipation. Every face of the electronics contributes to cooling.\n\n\u003cb\u003eAll-Round Lens Protection. Camera Kit Included.\n\u003c\/b\u003eBeyond cooling, the kit includes a 20mm camera mounting housing that provides all-round protection for the O4 Pro camera lens. The adapter shields the camera from impacts, debris, and crash damage while maintaining the standard mounting interface.\n\n\u003cb\u003eDual Mounting Patterns. Fits Every Frame.\n\u003c\/b\u003eTwo sets of mounting holes: 25.5×25.5mm (Φ2mm) and 20×20mm (Φ2mm) . Compatible with standard digital FPV frame stacks. Drops into frames designed for Vista, Link, and other digital VTX standards. No modification required.\n\n\u003cb\u003eV2 Design. Sturdy and Durablee.\n\u003c\/b\u003eThe V2 iteration refines the aluminum component dimensions to 32.1×32.1×9.8mm for the heatsink and 20×19.5×21.1mm for the camera housing. Nylon components provide electrical isolation where needed. The assembly is built to survive the vibrations, impacts, and thermal cycling of aggressive FPV flying.\n\n\u003cb\u003eKey Features\n\u003c\/b\u003e* CNC ALUMINUM ALLOY SHELL: Precision-machined heatsink. Replaces stock plastic housing. Efficient passive heat dissipation.\n\n* FULL-WRAP COOLING ARMOR: Top + bottom aluminum covers. Maximum surface area for thermal transfer.
