مخطط أطراف وحدة GPS NEO-6M (GY-NEO6MV2)
الأطراف
- VCC (3.3–5V — most GY-NEO6MV2 boards carry a 3.3V regulator)
- RX (module input — connect to the MCU TX)
- TX (NMEA sentences out, 9600 baud default)
- GND
- The PPS LED blinks once per second only after a satellite fix — first fix outdoors can take minutes
