NEO-6M GPS Module – High-Precision Satellite Positioning Module for Arduino, ESP32, and Embedded Systems The NEO-6M GPS Module is a compact and powerful satellite positioning unit based on the u-blox NEO-6M GPS chipset, designed for high-accuracy location tracking. It supports communication with multiple satellite systems (GPS, QZSS, SBAS) and delivers fast satellite acquisition and tracking, making it ideal for navigation, vehicle tracking, time synchronization, and location-aware IoT projects. This module comes with an onboard 25 x 25mm active ceramic antenna, a built-in EEPROM for saving configuration settings, and a backup battery (CR1220) to maintain real-time clock and satellite data during power loss for faster fix times. It communicates using standard UART (TX/RX) at 9600 baud and is fully compatible with Arduino, ESP32, STM32, and other microcontrollers. Key Features Based on u-blox NEO-6M GPS chipset High-sensitivity and fast acquisition time Includes onboard active GPS antenna Backup battery for quick startup and RTC support Built-in EEPROM for configuration storage Standard UART interface (9600 baud default) Compatible with Arduino, ESP32, Raspberry Pi, STM32, etc. LED indicator for fix status Product Specifications Feature Specification GPS Chipset u-blox NEO-6M Antenna Type 25 x 25mm Active Ceramic Antenna Positioning Accuracy 2.5 meters (CEP) Update Rate 1Hz (default), up to 5Hz configurable Cold Start Time ~27 seconds Warm Start Time ~25 seconds Hot Start Time ~1 second Interface UART (TX, RX) Default Baud Rate 9600 bps Operating Voltage 3.3V to 5V DC Backup Battery CR1220 (for saving ephemeris data and time) Dimensions ~25mm x 35mm (may vary slightly by board) Supported Protocols NMEA, UBX binary Compatible Platforms Arduino, ESP8266, ESP32, STM32, Raspberry Pi, etc. Applications GPS tracking systems Drone and UAV navigation Vehicle and asset tracking Geographic mapping and surveying Time synchronization for distributed systems Smart agriculture and location-aware IoT devices
