Holybro PM03D Power Module with I2C Digital Power Monitoring

The Holybro PM03D Power Module is a high-precision digital power management unit designed for Pixhawk 5X, 6X, and other flight controllers that support I2C-based power monitoring. By using I2C digital communication instead of analog voltage sensing, the Holybro PM03D Power Module provides cleaner, more accurate current readings, stable voltage telemetry, and improved noise immunity for advanced drone builds. It is not compatible with analog-based systems such as Pixhawk 4, Pixhawk 6C, Pix32 v5, Durandal, or their Mini versions.

Engineered for multirotors like the X500 V2, this module includes preinstalled XT-60 and XT-30 connectors for straightforward integration with batteries, ESCs, and peripherals. The onboard regulators offer two independent 5.2V BEC outputs plus a selectable 8V/12V output, making it ideal for powering companion computers, GPS units, cameras, and other mission-critical electronics. With a current sensing capability up to 164A and durable 12AWG XT60 wiring, the Holybro PM03D Power Module ensures reliable power delivery for demanding aerial platforms.

This module is fully plug-and-play with QGroundControl and Mission Planner, reducing setup time and eliminating configuration errors. Whether you are upgrading an existing aircraft or building a new system, the Holybro PM03D Power Module provides stable power, accurate telemetry, and dependable performance.
