Arduino GPS Shield
The Arduino GPS shield is a GPS module breakout board designed with a Global Positioning System receiver and SD card slot for recording position data. Its 5V and 3.3V operating voltages make it compatible with Arduino boards, leaf maple, IFlat32 and other Arduino compatible boards. It is a compact, high performance, and low power GPS engine board. It uses the SiRF Star III chipset which can track up to 20 satellites at a time and perform fast TTFF in weak signal environments.
