Matek Power Distribution Board with dual BEC 5V & 12V

Matek Power Distribution Board (PDB) with Dual BEC 5V & 12V is an essential component for multirotor and fixed-wing aircraft, centralizing power management and delivering clean, regulated voltage to sensitive electronics. This compact and high-efficiency board simplifies your wiring harness, allowing you to connect ESCs directly to the main battery input pads. Furthermore, it integrates two highly reliable Battery Eliminator Circuits (BECs) to provide simultaneous, regulated 5V and 12V outputs. The 5V BEC efficiently powers flight controllers, receivers, and GPS modules, while the 12V BEC conveniently supplies power to video transmitters (VTX) and FPV cameras. Consequently, this PDB is crucial for maximizing flight performance and minimizing potential electrical noise in complex FPV setups.

Key Features:

• Integrated Dual BECs: Features highly efficient, synchronous step-down voltage regulators to simultaneously produce stable 5V and 12V outputs.
• High Current Handling: The main power distribution section supports a continuous current of up to 4x25A or 4x30A (Burst), easily accommodating powerful multirotor setups.
• Built-in Filtering: The PDB design incorporates features that help filter out noise from the ESCs and motors, delivering clean power to the FPV system.
• Compact and Lightweight: Its small form factor and lightweight construction make it ideal for competitive racing drones and small aircraft where weight is critical.
• Wide Input Voltage Range: Accepts a broad range of input voltages, typically supporting 3S to 6S LiPo batteries (9V – 26V DC).
