My first bench tests were done when the shield was not attached to the Raspberry Pi GPIO. Powered by a ‘PL2303HX USB to COM/UART/TTL Integrated Programmer Cable’ had 5 volts (red) to GPIO pin 2, Ground (black) to pin 6, and serial data out (green) to pin 10, and therefore the dongle could be plugged into any system with a serial terminal at 9600 baud. The Shield does requires a ‘GPS Magnetic Active External Antenna w/ 3m cable’ which is also very convienient as the antenna can be placed outside a window.
As there is no lithium battery storing ephemeris data, a cold power will always take some time. The $GPRMC data = time showed after 8 seconds, date after 27 and full lat/long data after 1m40 seconds. With a full view of the sky the data will be much faster.
At this stage
