Holybro PM02 V3 12S Power Module

The Holybro PM02 V3 is a 12S-rated analogue power module that supplies regulated 5.2V to a Pixhawk or ArduPilot flight controller while reporting battery voltage and current draw over a single 6-pin JST-GH cable.

Key features

• Switching regulator delivers a clean 5.2V at up to 3A to the flight controller
• Analogue voltage and current sensing rated to 120A max, with a 60A continuous / 100A burst (under 60s) PCB rating
• Pre-soldered XT60 connectors on both ends plus heat-shrink tubing over the PCB for physical protection
• Ships with a 220uF capacitor and both Molex and JST-GH 6-position leads for PX4 and ArduPilot autopilots

Specifications

• Input voltage: 2S–12S LiPo (7-51 V)
• Output: 5.2V, 3A max
• Max current sensing: 120A
• PCB continuous current: 60A (100A burst, under 60s)
• Pre-fitted XT60 plugs and 12AWG leads: 30 A continuous, 60 A burst (under 60 s); fit a larger plug and wire for higher currents
• Voltage divider: 18.182
• Amperes per volt: 36.364
• Weight: 20g

Uses analogue output only, so it is not compatible with Pixhawk 5X or 6X flight controllers, which need the digital PM02D module instead; set the voltage divider and amps-per-volt values above in Mission Planner or QGroundControl for accurate battery readings.
