Software

Configuration Steps

• Default protocol: UBX over UART
• Configurable using u-blox u-center software
• Adjust:
  • Baud rate
  • Output frequency
  • GNSS constellation selection
  • Message types (NMEA / UBX)
  • Spoofing/jamming protection

Integration Steps

1. Connect VCC (3.3 – 12 V) and GND to your power source.
2. Connect UART or I²C lines to your flight controller or embedded system.
3. Mount securely to UAV frame using M3 bolts and spacers.
4. Configure the module with u-center or compatible software if needed.
