The GY-NEO-6M GPS Module is a compact and efficient GPS receiver based on the u-blox NEO-6M chipset, designed for accurate position tracking and navigation. It features an active ceramic antenna for strong satellite signal reception and includes an onboard EEPROM and backup battery to store configuration data and assist with faster position fixes after power cycles.
 
Key characteristics include
Input Voltage: 3.3V to 5V (onboard regulator)
Communication: TTL UART (default 9600 bps), NMEA sentences output
Update Rate: 1 Hz (configurable up to 5 Hz)
Position Accuracy: ~2.5 m CEP
Startup Time: Cold start ~27 s, warm start ~25 s, hot start ~1 s
Antenna: Active ceramic with IPX connector for strong reception
Features: LED indicators for power and GPS fix, 50-channel tracking, low power consumption (~45 mA)
It’s widely used in IoT, robotics, drones, navigation systems, and geolocation projects, and is compatible with Arduino, ESP8266, ESP32, Raspberry Pi, and other microcontrollers.
