This device is a simple GPS receiver that plugs into the USB port and outputs standard NMEA data. The USB GPS Receiver was designed to meet a few simple requirements:
- Output standard NMEA strings to the host computer via USB
- Smallest possible size
- Integrated antenna
The USB protocol is handled by a FTDI FT232BL. Drivers for all popular operating systems can be found here. The GPS receiver is a Leadtek LR9101LP and uses an on board passive antenna from Sparkfun Electronics. Download the Altium Designer project files here.
