MATEK Mateksys PDB-HEX 12S 5V&12V
Matek PDB-HEX 12S Power Distribution Board for Hexacopters & Large UAVs
The Matek Systems PDB-HEX 12S is a high-current power distribution board (PDB) engineered for hexacopters, heavy-lift multirotors and X-Class drones that use separate ESCs. It distributes battery power from a 2S–12S LiPo (6–60 V) to six independent ESC outputs, carries up to 140 A continuous / 264 A burst, and integrates a precise 264 A current sensor plus a 5 V/9 V/12 V adjustable BEC — all on a compact, 12 g board.
High-Current Power Distribution You Can Trust
- 140 A continuous, 264 A burst PDB/current-sense resistor for demanding powertrains
- Six ESC power pads rated 60 A continuous / 100 A burst each — one per motor arm
- Wide 6–60 V DC input (2S–12S LiPo) covers everything from long-range 6S builds to 12S heavy-lift platforms
- Short-circuit tolerant outputs (1 s), overcurrent protection with self-recovery
Built-In 264 A Current Sensor & 1:21 Voltage Divider
A high-precision current sensor with a 264 A range and 3.3 V ADC output feeds real-time current data straight to your flight controller, while the onboard 1K:20K voltage divider outputs 1/21 of pack voltage for accurate battery monitoring. No external sensor board or extra wiring harness required.
- Current scale 125 for Betaflight / INAV, BATT_AMP_PERVLT 80 for ArduPilot
- Direct connection to any spare MCU ADC pin
Adjustable 5 V / 9 V / 12 V BEC — Up to 5 A
The integrated switching regulator delivers a default 5 V / 5 A continuous output. Bridging the onboard solder jumper selects 9 V or 12 V (4 A continuous, 5 A burst) — ideal for powering flight controllers, HD video transmitters, cameras, servos and gimbals from a single rail. Outputs are short-circuit tolerant for one second and self-recover after an overcurrent event.
Clean Wiring: 6 ESC Pads + JST-SH-8P Flight Controller Link
Six labelled ESC power / signal / telemetry pads keep motor wiring tidy, and a pre-soldered JST-SH-8P connector (5 cm cable and two spare connectors included) carries Vbat, GND, Curr, Tlm and ESC signals S1–S4 to your flight controller in a single plug. All Tlm pads are shorted together for BLHeli32 ESC telemetry.
