Matek PDB-HEX, 12S compatible
by Matek Systems

The Matek PDB-HEX 12S is a high-performance power distribution board (PDB) designed for hexacopters, drones, and UAV applications. With an input voltage range of 6V to 60V (2-12S LiPo) and an impressive 140A continuous current capacity (264A burst), it ensures stable and efficient power distribution to your ESCs and flight systems.

This PDB supports six ESC power, signal, and telemetry connections, allowing seamless integration with modern flight controllers. It features a built-in 264A current sensor with a 3.3V ADC output, making it compatible with INAV, Betaflight, and ArduPilot.

The adjustable BEC output (5V default, 9V or 12V via jumpers) provides up to 5A continuous current, ensuring a reliable power source for servos, cameras, and flight controllers. The board also includes overcurrent protection, short-circuit tolerance, and self-recovery features, making it an ideal choice for demanding FPV and UAV setups.
