The “FCHUB-6S PDB” is a Power Distribution Board (PDB) designed for use in multirotor drones and other RC (Remote Control) aircraft. Here’s an overview of its key features and functionality:

1. Power Distribution:

  • 6S Compatibility: The “6S” designation indicates that the PDB is compatible with LiPo battery configurations up to 6S (6 cells in series), commonly used in high-performance drones.
  • Voltage Regulation: The PDB regulates and distributes power from the battery to various components of the drone, such as flight controllers, ESCs (Electronic Speed Controllers), motors, and other onboard electronics.

2. Current Monitoring:

  • Current Sensor: The PDB may include a current sensor to measure the current drawn by the entire drone or individual components.
  • Real-Time Monitoring: Pilots can monitor the current consumption of their drone in real-time through telemetry or OSD (On-Screen Display), helping to prevent overloading the system and ensuring safe operation.

3. Integrated Features:

  • Built-in BEC: Some PDBs incorporate a Battery Eliminator Circuit (BEC) to provide regulated voltage to power auxiliary components such as cameras, video transmitters, receivers, or LEDs.
  • LED Outputs: The PDB may include dedicated outputs for connecting LEDs or other lighting accessories for visibility and orientation during flight.

4. Layout and Design:

  • Compact Size: The PDB is designed to be lightweight and compact, allowing it to fit neatly within the frame of the drone without adding unnecessary bulk.
  • Mounting Holes: Mounting holes are provided for secure installation within the drone’s frame, ensuring stability and reliability during flight.

5. Compatibility:

  • Multirotor Drones: The FCHUB-6S PDB is suitable for use in a wide range of multirotor drones, including quadcopters, hexacopters, octocopters, and more.
  • Flight Controllers: Compatible with various flight controllers, ensuring seamless integration and communication between the PDB and flight control system.

6. Wiring and Connections:

  • Solder Pads: Components are typically soldered directly to the PDB using solder pads or tabs, providing a secure electrical connection.
  • Input and Output Ports: The PDB features input ports for connecting the battery and output ports for distributing power to individual components.


The FCHUB-6S PDB serves as a central power distribution hub for multirotor drones, ensuring efficient and reliable power delivery to all onboard electronics. With features such as 6S compatibility, current monitoring, integrated BEC, and compact design, it provides drone builders and pilots with the necessary power management capabilities for safe and successful flights. When combined with compatible components and properly installed within the drone’s frame, it contributes to a well-functioning and high-performance aerial platform.
