Holybro Power Distribution Board (PDB) 300A – Top Entry / Side Entry | XT90 XT30 High Current PDB for UAV Drones

Overview

The Holybro Power Distribution Board (PDB) 300A is engineered for high-current UAV, robotics, and industrial power applications, offering a robust and reliable power hub for multi-output setups. Supporting up to 300A continuous and 1000A burst current, this PDB is built with 10oz heavy copper PCB for exceptional heat dissipation and minimal resistance under heavy loads. Designed for seamless integration with PM08 series power modules, it’s ideal for drone power systems, electric vehicles, and other current-intensive platforms.

Two configuration options are available to suit different wiring and layout requirements:
