Holybro 300A Power Distribution Board PDB High-Current
Specifications
- Holybro 300A PDB is a heavy-duty high-current power distribution board built for large multirotor, industrial and agricultural UAV power systems. It supports 300A continuous current and 1000A burst current, adopting 10-oz thick copper PCB to lower internal resistance, reduce heat generation and avoid voltage drop under heavy-load flight conditions. Two hardware variants, top-entry and side-entry connector layout, are available to fit different drone wiring layouts and frame installation need
- Pre-soldered with multiple XT90 and XT30 high-current connectors, this PDB offers abundant output ports for ESCs and peripheral devices. High-current screw terminals allow reliable battery input connection, simplifying wiring assembly for large-size drone projects. It is well compatible with Holybro PM08-CAN power module, perfectly matching Pixhawk open-source flight control systems for industrial UAV.
- Optimized for high-power platforms, the thick copper layer delivers excellent heat dissipation performance during long-time full-throttle operation. M3 mounting holes reserve stable fixing positions for frame installation, helping prevent vibration loosening in field working environments. Compact PCB layout keeps neat power-loop wiring and effectively reduces electromagnetic interference for onboard sensors.
- It adapts to high-voltage multi-cell lithium battery systems widely used in plant-protection and inspection drones. Each output port maintains stable power supply for ESCs, gimbals and other payloads. Strict factory testing guarantees reliability for commercial UAV projects, avoiding burnout risks caused by over-current under actual flight loads.
- Designed for professional drone developers and system integrators, Holybro 300A PDB provides robust power distribution solution for heavy-lift multirotor . It balances high-current capacity, convenient assembly and flexible installation, widely applied in agriculture spraying, power inspection and custom industrial drone project.
