Product Description The NEO-7M GPS Module is a high-precision satellite positioning development board designed to provide location, altitude, and time data to your projects. Built on the advanced U-blox 7 architecture, this module offers faster acquisition times and lower power consumption than the older NEO-6M. It features an integrated high-gain ceramic passive antenna and an onboard EEPROM for saving configuration settings even after power-off. It is the preferred choice for flight controllers (like Pixhawk or APM), vehicle tracking systems, and long-range IoT data loggers.

Key Highlights
Superior Acquisition: The NEO-7M chipset can track multiple satellite constellations simultaneously, ensuring a stable "fix" even in urban environments with partial sky visibility.
Onboard Signal Indicator: Features a "PPS" (Pulse Per Second) LED that blinks once a satellite lock is achieved, allowing for easy visual debugging without a computer.
Integrated Battery Backup: Includes a small rechargeable MS621FE button cell to store "ephemeris" data, enabling "Hot Starts" that take less than 1 second to lock.
Plug-and-Play Serial: Outputs standard NMEA sentences (Global Positioning System Fix Data) over a simple UART interface, making it compatible with any microcontroller.
Large Ceramic Antenna: The module comes with a 25mm x 25mm ceramic patch antenna that provides excellent signal-to-noise ratios.

Prototyping & Installation Tip GPS signals are extremely weak and cannot penetrate concrete or metal. You must test this module outdoors or near a window with a clear view of the sky. On the first power-up (Cold Start), it may take 3-5 minutes to acquire satellites. For Arduino users, the TinyGPS++ library is highly recommended for parsing the complex NMEA data into simple Latitude and Longitude variables. When wiring, connect the Module's TX to the Arduino's RX, and the Module's RX to the Arduino's TX.
Note: This product includes the NEO-7M Board and a Ceramic Antenna. External SMA antennas can be attached to some versions via the IPEX connector. Product images are for illustration purposes only.
