NEO-6M V2 GPS Module for Microcontrollers
This is a simple GPS module that requires only four wires to get this gps module up and running with your Arduino Microcontroller!
Pin definition:
1, VCC: power supply (3.3V-5V)
2, GND: ground wire
3, TXD: module serial port to send pin (TTL level, can not be directly connected to the RS232 level, can be connected to the microcontroller RXD)
4, RXD: module serial port receive pin (TTL level, can not be directly connected to the RS232 level, can be connected to the microcontroller TXD)
5, PPS: clock pulse output pin.
