3. Setup and Installation
Proper installation of the PM03D Power Module is essential for the safe and reliable operation of your multi-rotor system. Follow these guidelines for setup.
Compatibility Note:
Important: This PM03D module is not compatible with flight controllers that use analog power modules, such as Pixhawk4, Pixhawk4 Mini, Pix32 v5, or Durandal flight controllers. It is designed for flight controllers that use I2C power monitoring, like Pixhawk 5X and up.
Connections:
- XT-60 Connector: For battery input. Ensure the XT60 plug and 12AWG wire are appropriate for your continuous and instantaneous current requirements. The included XT60 and 12AWG wire are rated for 30A continuous and 60A instantaneous (<1 minute). If higher currents are used, the plug type and wire size must be changed accordingly.
- XT-30 Connectors: For motor ESCs and peripheral devices requiring battery voltage. There are solder pads in each corner for additional battery voltage connections.
- CLIK-Mate 2.0mm 6-pin: Connects to the flight controller (provides 5.2V/3A standalone BEC).
- JST GH 4-pin: For powering companion computers (5.2V/3A, BEC shared with 5.2V triple row pin header).
- Triple Row Pin Headers (5.2V): Two sets, providing 5.2V/3A (BEC shared with JST GH 4-pin).
- Triple Row Pin Headers (8V or 12V): Two sets, selectable by moving a header jumper, providing 3A.

4. Operating Instructions
Once properly installed and connected, the PM03D Power Module operates with minimal user intervention. It is designed for plug-and-play functionality with compatible flight controllers and ground control software.
Basic Operation:
- Connect your flight battery to the XT-60 input.
- Ensure all ESCs and peripheral devices are correctly connected to the XT-30 or other designated output ports.
- The module will provide regulated power to the flight controller and connected peripherals.
- Current and voltage data will be transmitted to the flight controller via the CLIK-Mate cable for monitoring in QGroundcontrol or Mission Planner.
Current Considerations:
Pay close attention to the current ratings. The XT60 plug and 12AWG wire supplied with the PM03D are rated for 30A continuous current and 60A instantaneous current (for less than 60 seconds). If your application requires higher currents, it is imperative to upgrade the plug type and wire size accordingly to prevent overheating and potential damage.
5. Maintenance and Care
To ensure the longevity and optimal performance of your PM03D Power Module, follow these maintenance and care guidelines:
- Regular Inspection: Periodically inspect all connections, including XT-60, XT-30, and other cable connections, for any signs of wear, corrosion, or loose contacts.
- Cleanliness: Keep the module free from dust, dirt, and moisture. Use a soft, dry brush or compressed air to clean the board if necessary. Avoid using liquid cleaners.
- Temperature Management: Ensure adequate airflow around the module during operation, especially under high current loads, to prevent overheating.
- Wire Integrity: If you modify the wiring for higher current applications, ensure that all solder joints are strong and insulated properly. Use high-quality, appropriately gauged wires.
- Storage: When not in use, store the module in a dry, cool environment, away from direct sunlight and extreme temperatures.
6. Troubleshooting
If you encounter issues with your PM03D Power Module, consider the following troubleshooting steps:
No Power to Flight Controller/Peripherals:
- Check Battery Connection: Ensure the XT-60 battery input is securely connected and the battery is charged.
- Verify Cable Connections: Confirm that the CLIK-Mate cable to the flight controller and all peripheral cables are correctly and firmly seated.
- Inspect for Damage: Look for any visible damage to the board, wires, or connectors.
Incorrect Voltage/Current Readings:
- Flight Controller Compatibility: Double-check that your flight controller uses I2C power monitoring. This module is not compatible with analog PM systems (e.g., Pixhawk4, Pixhawk4 Mini, Pix32 v5, Durandal).
- Software Configuration: While designed for plug-and-play, ensure no conflicting settings in your flight controller's ground control software (QGroundcontrol/Mission Planner).
- Sensor Calibration: If readings are consistently off, consult your flight controller's manual for power module sensor calibration procedures.
Overheating:
- Current Overload: Ensure your system's current draw does not exceed the module's rated continuous or instantaneous limits. If it does, upgrade the XT60 connector and battery wires to a higher gauge.
- Ventilation: Confirm the module has adequate airflow and is not enclosed in a way that traps heat.
