Connecting GPS Breakboard with Raspberry Pi 3

Connect u-Blox NEO-6M GPS module board to Raspberry Pi 3 via UART. Connect TX pin from moudle to RPi RX pin (pin 10/GPIO 15) and RX pin on module to RPi TX pin (pin 08/GPIO 14). Connect 3.3 V RPi pin (pin 01) to VCC of the module board and also the ground to RPi (pin 06).
