RXM-SG GPS Module w/Ext Antenna (#28505)
The RXM-SG GPS Module provides a high quality, highly sensitive GPS receiver with an external antenna
to provide a complete GPS solution for both microcontroller and PC applications. The high-performance
SiRFstar III chipset features 20 parallel satellite tracking channels for fast acquisition of NMEA0183 data
for robotics navigation, telemetry or experimentation. This GPS Module can connect to a microcontroller
or even a PC (via USB). A Windows application provides a graphical display of the GPS data and can
even show your location on Google Maps (internet connection required). Four general purpose I/O pins
provide expansion for pin-intensive projects.
