I have a ublox-6m-0-001 GPS Shield and I'm using TinyGPSPlus.
All code samples shipped with TinyGPSPlus use SoftwareSerial hooked to pins 4 (RX) and 3 (TX) with a 4800 Baud Rate.
That doesn't quite work right away, so I've replaced the SoftwareSerial with Serial3 and hooked the shield to pins 15(RX) and 14 (TX) with 9600 Baud Rate.
Code sample available at examples/GPS.ino.
| Shield | Arduino |
|---|---|
| VCC | 3.3V |
| GND | GND |
| TX | Pin 15 (RX3) |
| RX | Pin 14 (TX3) |
