Holybro PM03D Power Module Without XT30 Pre-soldered
by Holybro

Note: This version (15017A) does NOT includle XT30 connectors of any sort. 

The Holybro PM03D Power Module - Without XT30 Pre-soldered (SKU: 15017A) is an integrated digital power module and power distribution board (PDB) engineered specifically for enterprise multirotors and autonomous UAV platforms powered by Pixhawk 5X and Pixhawk 6X flight controllers. Unlike traditional analog power modules, the PM03D transmits high-precision digital voltage and current telemetry to the autopilot over an I2C bus, delivering plug-and-play calibration with PX4 and ArduPilot in QGroundControl and Mission Planner without requiring manual scale or offset tuning.

This specific variant (Variant: 42753360887997 / SKU: 15017A) omits the pre-soldered female XT30 ESC connectors, providing open solder pads at each corner for direct soldering of motor ESC power leads or custom wiring harnesses. Designed for 2S to 6S LiPo power, the PM03D features three independent onboard voltage regulators—a dedicated 5.2V/3A BEC for the autopilot, an auxiliary 5.2V/3A BEC for companion computers and accessories, and a selectable 8V/12V (3A) regulator for HD video transmitters, gimbals, and high-voltage peripherals.

Key Features

• Open Solder Pad Layout (SKU: 15017A): Leaves ESC power pads unpopulated by XT30 connectors, enabling direct-soldered ESC wiring to minimize weight, reduce vertical stack height, and eliminate intermediate connectors.

• I2C Digital Telemetry Monitoring: Delivers calibrated digital voltage and current telemetry directly to Pixhawk 5X/6X autopilots without analog signal noise or manual resistor calibration.

• Triple Regulated BEC Outputs: Features two independent 5.2V/3A regulators (one dedicated to the flight controller, one for companion computers) and one jumper-selectable 8V/12V (3A) regulator for FPV gear and peripherals.

• Broad Peripheral Harnessing Support: Includes plug-and-play adapter cables for USB Type-C and barrel jack connectors to easily power companion computers like Raspberry Pi, Jetson Nano, or Khadas boards.

• Integrated ESC Power Distribution: Built-in heavy-copper PDB traces handle up to 60A continuous (120A burst) total current draw across multirotor motor arms.

• Pre-Soldered Noise Filtering: Comes factory-equipped with a 220µF 63V low-ESR electrolytic capacitor and pre-soldered 12AWG XT60 battery leads.
