Concept
A GNSS receiver listens to satellites and prints NMEA sentences over UART.
A little theory
Needs sky view. Cold start minutes; backup battery helps warm start. 1 pulse-per-second on some boards. In the classroom, treat u-blox NEO-6M GPS Module as a intermediate part using UART NMEA 9600. Typical India street price is about ₹350–₹700. Always verify voltage and pin labels on your exact module — silk screens vary across clones. Start with a datasheet or trusted learn guide, power the part correctly, share GND with the MCU, and test with a simple blink/read sketch before building the full project. Measure voltages with a multimeter when something fails, and keep actuator current off the MCU regulator.
