The GY-NEO-6M GPS Module is a compact GPS positioning module designed for obtaining real-time location, speed, altitude, and timing information. Based on the u-blox NEO-6M GPS receiver, it communicates with Arduino, ESP32, STM32, and other microcontrollers through a UART serial interface. It is widely used in GPS trackers, robotics, drones, vehicle tracking, navigation systems, and IoT projects.
