4. Setup and Installation

The M10-25Q GPS module offers two primary connection methods: direct plug-in using the SH1.0-6P connector or soldering to PCB pads. It is recommended for use with INAV firmware.

4.1 Wiring Diagram

Important: Ensure correct wiring before applying power to prevent potential damage to the product or connected components.

Image 8: Wiring diagrams for the SEQURE M10-25Q GPS module, showing connections for both SH plug-in socket and direct soldering to a Flight Controller (FC). The diagram details connections for TX, RX, GND, V (5V), SCL, and SDA.

4.2 Connection Pinout

• TX: Transmit Data (Connect to RX on Flight Controller)
• RX: Receive Data (Connect to TX on Flight Controller)
• GND: Ground
• V (5V): Power Input (5V)
• SCL: I2C Clock Line (for Compass)
• SDA: I2C Data Line (for Compass)

For plug-and-play convenience, use the provided SH1.0-6P connector. If your flight controller requires a different pin arrangement, you may need to carefully re-pin the connector or use the soldering pads. Always verify pin assignments with your flight controller's documentation.

5. Operation

5.1 Initial Power-Up and Satellite Acquisition

Upon initial power-up, place the drone in an open area with a clear view of the sky. The GPS module will begin searching for satellites. The M10-25Q is designed for fast positioning, typically acquiring a lock within a minute under optimal conditions.

5.2 Output Protocols and Frequency

• The module outputs data using both NMEA and UBX protocols.
• The default output frequency is 10Hz, which can typically be configured via your flight controller's software (e.g., Betaflight, INAV).
• The QMC5883L compass data is transmitted via the I2C interface.

5.3 Flight Controller Configuration

Refer to your specific flight controller's firmware documentation (e.g., INAV, Betaflight) for detailed instructions on enabling and configuring GPS and compass functionality. This typically involves:

• Enabling the GPS UART port and selecting the correct baud rate (115200).
• Enabling the I2C port for the compass.
• Setting the correct GPS protocol (UBLOX or NMEA).
• Calibrating the compass as per the flight controller's instructions.

6. Maintenance

The SEQURE M10-25Q GPS module is designed for durability and requires minimal maintenance. Keep the module clean and free from dust and debris. Avoid exposing it to extreme physical shock or moisture beyond its specified operating conditions. Ensure all connections remain secure.

7. Troubleshooting

• No GPS Lock or Slow Acquisition:
  • Ensure the drone is in an open outdoor area with a clear view of the sky.
  • Verify all wiring connections (TX to RX, RX to TX, GND, 5V) are correct and secure.
  • Check flight controller configuration for correct UART port, baud rate (115200), and GPS protocol settings.
  • Ensure there is no significant electromagnetic interference from other drone components. Consider shielding the GPS cable with metal tape if interference is suspected.
• Incorrect Compass Heading:
  • Verify I2C connections (SCL, SDA, GND, 5V) are correct.
  • Perform a compass calibration as per your flight controller's instructions.
  • Ensure the compass is mounted away from strong magnetic fields (e.g., motors, power wires).
• Module Not Detected by Flight Controller:
  • Double-check all wiring for continuity and correct pin assignment. Some flight controllers may require re-pinning the connector.
  • Confirm the flight controller's UART and I2C ports are enabled in the firmware configuration.
  • Ensure the module is receiving the correct 5V power supply.
