U-blox NEO-7M GPS Satellite Positioning Module – High-Performance Navigation Board with Integrated EEPROM and Ceramic Antenna for Arduino & STM32

Technical Details

• Receiver Type: 56-channel engine supporting GPS L1 C/A, GLONASS L1 FDMA, QZSS L1 C/A, and SBAS (WAAS, EGNOS, MSAS).

• High Sensitivity: Tracking sensitivity of -162 dBm and Cold Start sensitivity of -148 dBm for indoor/obstructed environments.

• Update Rate: Supports a maximum navigation update rate of up to 10 Hz, ideal for high-speed aerial platforms.

• UART Communication: Standard serial pins (TX/RX) provide easy interfacing with Arduino, STM32, ESP32, and Raspberry Pi.

• Velocity Accuracy: Provides precise ground speed measurements with an accuracy of 0.1 m/s.

• Heading Accuracy: Capable of determining dynamic heading with a resolution of 0.5 degrees.

• Power Supply Regulator: Integrated LDO allows the module to accept a 3.3V to 5V input while protecting the 3V core logic.

• Antenna Connectivity: Includes a U.FL (IPEX) connector for switching to an external high-gain active antenna if required.

• Operational Limits: Designed for high-altitude tracking up to 50,000 meters and velocities up to 500 m/s.

• Horizontal Positioning: Achieves a standard circular error probability (CEP) of 2.5 meters.

• Data Logging: Compatible with u-center software for advanced real-time visualization and performance analysis.

• NMEA Protocol: Outputs standard NMEA-0183 messages ($GPRMC, $GPGA, etc.) for universal software compatibility.

• Timing Accuracy: Provides a highly accurate 1PPS (Pulse Per Second) signal synced to GPS time via a dedicated pin.

• Logic Level Shifting: On-board resistors ensure serial lines are compatible with most 3.3V and 5V microcontrollers.

• Industrial Build: Operates reliably across a wide temperature range from -40°C to +85°C.

Prototyping and Engineering Tips from Robogears

• 9V Battery Use: Do not connect a 9V battery directly to the module. Always power the GPS module from the regulated 5V or 3.3V pin of your development board.

• 18650 Cell: A single 18650 cell is an excellent choice for portable trackers. We suggest placing a 100uF electrolytic capacitor across VCC and GND to prevent resets during signal search.

• IC & Capacitor Tip: GPS modules are sensitive to electromagnetic noise. Keep the module away from high-power WiFi antennas and switching DC-DC converters. For the best first-time fix, place the module under a clear sky for at least 5-10 minutes.

• Related Products: We recommend pairing this with our MicroSD Card Modules for data logging, 16x2 I2C LCDs for coordinates display, and Drone Flight Controllers.
