Notes

SiRFstarV is our industry leading GNSS receiver tracking both GPS and Glonass satellites. The mbed Shield is fitted with the OriginGPS module (ORG4572) requiring a 1V8 supply, ground, UART interface and connection to GNSS capable antenna. Additional IOs are available for interrupts, turning the receiver on and off, reset, fix status and power mode information.
