Description
The APM Power Module is an essential accessory for ArduPilot-based flight controllers like APM 2.x, Pixhawk, and PX4. It serves two critical functions: it provides a clean, regulated 5.3V power supply to the flight controller and allows the autopilot to monitor battery voltage and current consumption in real-time . By integrating a switching BEC with a voltage/current sensor, this module simplifies wiring and enables essential safety features like low-voltage return-to-launch . The module comes fully assembled with XT60 connectors for plug-and-play integration with LiPo batteries and power distribution boards
Key Features
- Voltage and Current Monitoring: Provides real-time battery voltage and current draw data to the flight controller for remaining power calculation and low-battery failsafes
- Integrated BEC: On-board switching regulator outputs a stable 5.3V DC at up to 3A to power the flight controller, receiver, and accessories like GPS modules
- High Current Sensing: Capable of measuring up to 90A, suitable for a wide range of multirotor and fixed-wing aircraft
- Plug-and-Play Design: Comes with pre-soldered XT60 connectors for the battery and ESC/PDB, plus a 6-position DF13 cable that plugs directly into the flight controller's power port
- Wide Battery Compatibility: Typically supports 2S to 4S LiPo batteries (up to 6S on some variants)

Application
- Drone Flight Controllers: Powers APM 2.5/2.6/2.8, Pixhawk, PX4, and Naze32-based autopilots
- Battery Monitoring: Provides telemetry data on remaining battery capacity and estimated flight time
- Power Distribution: Simplifies wiring by providing a central connection point between the battery, power module, and ESC/PDB
- Unmanned Aerial Vehicles (UAVs): Essential for reliable power delivery and current monitoring in both multirotor and fixed-wing aircraft
