Product Description The u-blox NEO-6M GPS Module is a world-renowned, high-performance satellite receiver used for global positioning and timing. It features the powerful NEO-6M engine, which can track up to 22 satellites and identify locations anywhere on Earth with remarkable accuracy. This module comes integrated with a high-gain ceramic patch antenna (often connected via a U.FL connector), ensuring a strong signal lock even in urban environments with tall buildings. At Robogears, we consider this the "industry standard" for building vehicle tracking systems, altitude-controlled drones, and time-synchronized clocks for IoT data logging.
Key Highlights
Standalone Operation: Features a built-in EEPROM for saving configuration settings and a battery backup for the Real-Time Clock (RTC), allowing for faster "Hot Starts" (re-acquiring satellite lock in seconds).
Serial TTL Communication: Communicates using simple NMEA sentences via UART, making it compatible with virtually every microcontroller including Arduino, ESP32, and STM32.
Onboard Signal Indicator: Includes an onboard LED that blinks once a "3D Fix" is established, providing immediate visual status without needing to check a computer monitor.
Active Antenna Support: While it comes with a ceramic antenna, the U.FL connector allows for the attachment of larger, external active antennas for high-shielding environments.
Compact Integration: The breakout board includes a 3.3V LDO regulator and level-shifting components, making it safe to use with both 3.3V and 5V power sources.

Installation Tip from Robogears GPS modules work on line-of-sight with satellites. For the first-time "Cold Start," you must be outdoors with a clear view of the sky; indoor testing will likely fail to get a lock. Connect the module's TX to the Arduino's RX and RX to TX (cross-connection). We highly recommend using the TinyGPS++ library to easily parse the raw NMEA data into usable Latitude, Longitude, and Speed variables. If the onboard LED isn't blinking, it means the module hasn't found enough satellites yet—be patient, as the first lock can take up to 5–10 minutes depending on your location.
