Flytex FCHUB12S PDB power distribution board

Flytex FCHUB12S — High-current PDB for large drones and X-Class platforms

Flytex FCHUB12S is a powerful power distribution board designed for heavyweight and high-thrust drones. It is designed to work with batteries up to 12S LiPo and provides stable power to all onboard systems even under extreme loads.

The board is equipped with integrated stabilizers, sensors, and reliable power tracks, allowing you to create a compact and safe power module for FPV platforms, X-Class aircraft, hybrid wings, and other high-performance UAVs.

Key Features Supports up to 12S
power Large cross-section power buses and copper traces withstand high currents without overheating, which is critical for large propellers and powerful ESCs.

Integrated dual BEC 5V
5A BEC for powering receivers, telemetry systems, and peripherals 12V 5A BEC for video transmitters, cameras, and additional electronics Both lines are stabilized and protected. Built-in current and voltage measurement The board transmits accurate power consumption data to the controller: — battery voltage measurement — high-precision current sensor This allows you to control consumption, predict battery life, and ensure that failsafe algorithms work correctly.
