Holybro PM03D Power Module
by Holybro

The Holybro PM03D Power Module (SKU: 15017) is an all-in-one digital power management unit and power distribution board (PDB) engineered specifically for Pixhawk 5X, 6X, and modern autopilots utilizing I²C-based digital power monitoring. By transmitting voltage and current metrics via the I²C protocol through a 6-pin Molex CLIK-Mate connection rather than analog signals, the PM03D provides clean, noise-immune telemetry without requiring manual calibration in QGroundControl or Mission Planner.

Designed for multirotor frames such as the Holybro X500 V2, the board integrates pre-soldered XT60 battery leads and XT30 motor ESC connectors alongside corner solder pads. The PM03D features three independent BEC power rails—two 5.2V/3A regulators for the flight controller and peripherals (companion computers, GPS) plus a jumper-selectable 8V/12V 3A regulator for cameras and video transmitters—delivering a plug-and-play power infrastructure for 2S to 6S LiPo builds.

Key Features

• I²C Digital Telemetry: Communicates voltage and current draw via digital I²C signals for high-accuracy telemetry without analog noise or manual sensor scaling.

• Integrated Power Distribution Board (PDB): Features pre-soldered XT60 input connectors, XT30 ESC ports, and heavy-duty corner solder pads for streamlined ESC wiring.

• Triple Independent BEC Regulators: Delivers two isolated 5.2V/3A power rails and one jumper-selectable 8V/12V 3A power rail for flight controllers, companion computers, and VTX systems.

• Plug-and-Play Pixhawk 5X/6X Compatibility: Works out-of-the-box with QGroundControl and Mission Planner when paired with Pixhawk FMUv5X and FMUv6X standards.

• High-Current Handling: Rated for 60A continuous (120A burst for <60s) with current sensing capabilities up to 164A across 2S to 6S LiPo battery packs.

• Flexible Peripheral Outputs: Includes JST-GH 4-pin ports, triple-row pin headers, and barrel plug adapter cables to power external companion hardware (e.g., Raspberry Pi, Jetson Nano).
