Arduino Compatible GPS Receiver Module – On-Board Antenna, Micro USB

You need a position fix, but you don't want to hunt down a matching external antenna and wire it up before you can even test the board. This module ships with an on-board ceramic antenna, so you plug in a micro USB cable, charge the tiny battery for about an hour, and you're getting 1 Hz fixes at 9600 baud. An SMA connector is there if you want to swap in your own antenna for better reception – just remove the C2 capacitor first, or the two antennas will fight each other and wreck your positioning. A reserved serial port means you can drop it into a larger MCU build without extra USB-serial converters. Works at 3.3 V or 5 V, uses the TinyGPS++ library, and has a signal LED so you know it's actually locked on
