DFRobot's Gravity Quectel-L76K GNSS positioning module supports single and multi-system positioning, delivering data like longitude, latitude, altitude, and time quickly. Multi-system combo offers higher precision/faster speed than single GPS (more satellites), stable in complex urban areas. With I2C/UART outputs, it works with Arduino, ESP32, Raspberry Pi. Ideal for outdoor scenarios: vehicle navigation, handheld trackers, item tracking, weather stations.
