MATEKSYS Mini Power Hub PDB with 5V & 12V BEC

The MATEKSYS Mini Power Hub is a 36 × 36 mm power distribution board that feeds four ESCs from a single 3S–6S LiPo and adds regulated 5 V and 12 V outputs for the flight controller, receiver, camera and video transmitter. It suits quads running four individual ESCs, or any build that needs clean BEC power in a tight space.

Key features

• Four ESC outputs rated 20 A continuous each, 25 A peak for 10 seconds per minute
• Synchronous buck regulators up to 95% efficient, with TVS protection on their input
• 5 V 3 A rail for receiver, flight controller, OSD and servos; 12 V 2 A rail for camera and VTX
• Both BEC outputs tolerate short circuits (10 seconds per minute) and carry LEDs that light when in regulation
• Solder bridges select camera and VTX voltage; video passes through from the CAM pad to the VTX pad
• 4-layer PCB with 2 oz copper for high current handling

Specifications

• Input: 3S–6S LiPo (9–26 V DC)
• ESC outputs: 4 × 20 A continuous, 25 A peak (10 s per minute)
• 5 V BEC: 5.0 V ±0.1 V, 3 A continuous
• 12 V BEC: 12.0 V ±0.2 V, 2 A continuous (3 A for 10 s per minute), needs 4S–6S
• Dimensions: 36 × 36 mm
• Mounting: 30.5 × 30.5 mm
• Weight: 6 g

On 3S the 12 V regulator has no headroom, so bridge the CAM/VTX pad to VCC to run 12 V-rated cameras and transmitters straight from the battery. On 4S–6S choose the 12 setting, and use the 5 setting for a 5 V camera on any cell count.
