Matek PDB FCHUB-12S V2 for Xclass
by Matek Systems

The Matek XCLASS PDB FCHUB-12S is a high-performance power distribution board (PDB) designed for X-Class racing drones, large UAVs, and heavy-lift multirotors. With an input voltage range of 8V to 60V (3-12S LiPo), this PDB efficiently delivers power to your ESCs, flight controllers, and onboard systems.

Supporting up to 4x 70A continuous current (110A burst) per ESC pad, this board is built for high-power applications. It integrates a 440A current sensor with a 3.3V ADC output for real-time power monitoring. Additionally, it features BEC outputs at 5V, 12V, and 3.3V, providing stable power for flight controllers, servos, video transmitters (VTX), and LED systems.

With ESC telemetry support, overcurrent protection, and self-recovery features, the FCHUB-12S is a reliable and efficient power hub for high-performance drones and UAVs.
