Holybro Power Module PM02
The Holybro Power Module PM02 is a compact power distribution and monitoring solution designed for unmanned aerial vehicles and autonomous systems requiring reliable voltage regulation and current sensing. Professional drone pilots, roboticists, and aerospace engineers rely on this module to ensure stable power delivery to flight controllers, sensors, and peripheral devices while maintaining real-time telemetry data. This module solves critical power management challenges by providing integrated voltage conversion, current monitoring, and safety features that prevent system failures due to power fluctuations or short circuits.
Product Overview
The Holybro PM02 Power Module operates as an intelligent power distribution hub that sits between your battery pack and flight controller or main processing unit. It features integrated XT60 connectors for battery input and multiple output ports with built-in voltage regulators that deliver clean, stable power at 5V and 12V rails. The module incorporates precision current sensors that measure real-time power consumption, enabling flight controllers to calculate remaining flight time, monitor system health, and trigger failsafe mechanisms when battery voltage drops below critical thresholds. The dual-output design allows simultaneous powering of flight controllers and auxiliary systems without voltage conflicts or ground loops.
What distinguishes the PM02 from generic power distribution boards is its integrated analog-to-digital conversion circuitry that feeds voltage and current telemetry directly to autopilot systems via dedicated signal pins. The module includes reverse polarity protection, over-current protection, and electromagnetic interference filtering to ensure reliable operation in electrically noisy environments. Its compact form factor and lightweight design make it ideal for weight-sensitive applications like small quadcopters, fixed-wing aircraft, and ground rovers where every gram impacts performance and flight duration.

How to Use
Installation of the Holybro PM02 begins with connecting your battery pack to the XT60 input connector, observing correct polarity as marked on the module housing. Route the 5V and 12V output cables to your flight controller and peripheral devices respectively, ensuring all connections are secure and free from moisture. The telemetry signal wire should be connected to your autopilot's power module input pin, typically labeled as POWER or PM on Pixhawk-compatible controllers. Before powering on, verify that no exposed conductors are present and that the module is mounted away from high-temperature components like motor speed controllers.
Once powered, configure your autopilot software to recognize the power module telemetry input and set appropriate voltage divider ratios and current sensor calibration values according to Holybro's documentation. Most modern autopilots like Pixhawk automatically detect the PM02 and require minimal configuration beyond selecting the correct power module type in firmware settings. Monitor the telemetry data in your ground station software to confirm voltage and current readings are accurate, then perform a bench test with known loads to validate sensor calibration before deploying on actual flights or missions.
Frequently Asked Questions
What is the maximum input voltage the PM02 can handle safely?
The Holybro PM02 is rated for input voltages up to 60V DC, making it compatible with LiPo battery configurations from 2S (7.4V nominal) through 14S (51.8V nominal). However, always verify your specific battery pack voltage rating and ensure it does not exceed the module's maximum specification. Operating beyond 60V input will damage the internal voltage regulators and sensing circuits.
Can the PM02 power both a flight controller and a companion computer simultaneously?
Yes, the PM02's dual output design allows simultaneous powering of a 5V flight controller and a 12V companion computer or high-power servo system. The 5V rail provides 3A continuous output while the 12V rail provides 2A, allowing you to power a Pixhawk flight controller and a small Jetson Nano or similar 12V device without exceeding individual rail limits. Calculate your total power requirements and ensure they do not exceed these specifications.
How accurate is the current sensing in the PM02?
The PM02 features a precision current sensor with 0.1A resolution across its 0-200A measurement range, providing approximately 0.5% accuracy under normal operating conditions. This level of accuracy is sufficient for flight time estimation and battery management in most UAV applications. For high-precision energy monitoring or research applications requiring better than 1% accuracy, external high-precision current shunts may be necessary.
Is the PM02 compatible with Pixhawk and ArduPilot systems?
Yes, the Holybro PM02 is fully compatible with all Pixhawk-series flight controllers and ArduPilot-based autopilots. The JST-GH telemetry connector matches standard power module inputs, and the analog voltage and current signals integrate seamlessly with Pixhawk's power management subsystem. Firmware configuration requires selecting Holybro PM02 as the power module type in Mission Planner or QGroundControl.
