NEO-6M GPS with Arduino Mega 2560 R3

Wiring for the NEO-6M GPS module (GY-NEO6MV2) on the Arduino Mega 2560 R3 (ATmega2560, 5 V logic), chosen with the same pin rules BoardPilot uses: default buses first, and no pins that are used for flash, USB, the debugger or booting.

Wiring

Check before you power it on

• Supply: 5 V from the 5V pin.

Test code (Arduino)

// Library: SoftwareSerial (built in)
#include <SoftwareSerial.h>

SoftwareSerial gps(10, 11);  // RX, TX (on the Mega, RX must be 10-13, 50-53 or A8-A15)

void setup() {
  Serial.begin(115200);
  gps.begin(9600);
}

void loop() {
  while (gps.available()) Serial.write(gps.read());  // NMEA sentences, e.g. $GPGGA
}

Questions

Which Arduino Mega 2560 R3 pins do I use for the NEO-6M GPS?

VCC → 5V, RX → ~11 (PB5), TX → ~10 (PB4), GND → GND.

Does the NEO-6M GPS work with the Arduino Mega 2560 R3 at 5 V?

Yes: the NEO-6M GPS runs at 3.3-5 V and the Arduino Mega 2560 R3 uses 5 V signals, so no level shifting is needed.
