How to Use Mini Power Hub: Examples, Pinouts, and Specs

The Mini Power Hub, manufactured by Matek, is a compact power distribution board designed primarily for use in small unmanned aerial vehicles (UAVs), such as quadcopters and other multirotors. It efficiently distributes power from a single battery source to multiple electronic components, such as flight controllers, ESCs (Electronic Speed Controllers), motors, and auxiliary devices. Its small footprint and lightweight design make it ideal for space-constrained applications where efficient power distribution is crucial.

1. Power Input Connection: Connect the battery's positive and negative terminals to the respective battery input pads on the Mini Power Hub.
2. ESC/Motor Connections: Connect each ESC's power leads to the corresponding positive and negative output pads. Ensure that the polarity is correct to prevent damage.
3. BEC Connections: Utilize the 5V BEC output to power electronic components such as flight controllers, and the 12V BEC output for FPV equipment or other 12V accessories.
4. Mounting: Secure the Mini Power Hub to your frame using the mounting holes provided. Ensure it is mounted away from high-vibration areas and propeller strike zones.

• Always verify the polarity of all connections to avoid short circuits.
• Do not exceed the maximum current ratings for the board and BEC outputs.
• Use appropriate gauge wires for the current draw of your components.
• Insulate exposed solder joints with heat shrink tubing to prevent shorts.
• Check for any signs of damage or wear before each use, and replace if necessary.

• Power Hub Overheating: Ensure that the current draw does not exceed the specified limits and that there is adequate airflow around the board.
• Voltage Irregularities: Check all solder joints and connections for shorts or poor contacts.
• Components Not Powering On: Verify that all devices are correctly connected with the right polarity and that the input voltage is within the specified range.

• If a component is not working, disconnect it and test with a multimeter to ensure it is receiving the correct voltage.
• In case of a short circuit, immediately disconnect the battery and inspect the board for solder bridges or exposed wires.
• For persistent issues, consult the manufacturer's support resources or community forums for assistance.

Q: Can I use the Mini Power Hub with a 6S LiPo battery? A: Yes, the Mini Power Hub supports a voltage range from 2S to 6S LiPo batteries.

Q: What should I do if the BEC is not outputting the correct voltage? A: Check the input voltage and solder joints. If the problem persists, the BEC may be damaged and the board might need replacement.

Q: Is it possible to use the 12V BEC output for 5V devices? A: No, you should only connect 12V rated devices to the 12V BEC output. Using it for 5V devices can damage them.

Q: How do I ensure the longevity of my Mini Power Hub? A: Avoid overloading the board, ensure proper soldering, and protect it from physical damage and moisture.
