Key Features of Matek PDB-HEX 12S BEC

Power Distribution and Current Sensing

With an input voltage range of 6V to 60V (2-12S LiPo), the Matek PDB-HEX 12S ensures smooth power distribution across all components. It can handle continuous currents of up to 140A and bursts up to 264A, making it suitable for high-powered builds. The ESC power pads support up to 60A continuous and 100A burst, ensuring your drone operates efficiently even under intense conditions.

• Input voltage range: 6~60V (2~12S LiPo)
• PDB/current sense resistor: 140A continuous, 264A burst
• ESC power pads: 60A continuous, 100A burst
• Current Sensor: 264A, 3.3V ADC
• Current Scale: 125 (INAV/BF), BATT_AMP_PERVLT 80 (ArduPilot)

JST-SH-8P Connector and Pads

The Matek PDB-HEX includes a JST-SH-8P connector for easy connections to your drone's ESCs and battery. This connector provides clear voltage, ground, current signal, and telemetry data for enhanced performance tracking.

• Vbat: Battery voltage
• G: Ground
• Curr: Current signal
• Tlm: ESC telemetry
• S1-S6: ESC signal
• Vx: Regulator Output

BEC Vx Output (5V default)

The BEC Vx output is set to 5V by default and can be adjusted to 9V or 12V using the onboard jumpers. It provides continuous power of up to 5 Amps, making it a reliable power source for additional components like FPV systems or flight controllers.

• Vx = 5V by default, continuous 5A
• Vx = 9V with jumper, continuous 4A, max 5A
• Vx = 12V with jumper, continuous 4A, max 5A
• Output short-circuit tolerant for 1 second
• Overcurrent protection and self-recovery

Voltage Divider

The built-in voltage divider uses 1K:20K resistors to output 1/21 of the Vbat voltage, providing precise voltage readings and telemetry data.
