The GP-20U7 accurately provides position, velocity, and time readings as well possessing high sensitivity and tracking capabilities. Thanks to the low power consumption this receiver requires, the GP-20U7 is ideal for portable applications such as tablet PCs, smart phones, and other devices requiring positioning capability.<\/p>\n<p>This 56-channel GPS module, that supports a standard NMEA-0183 and uBlox 7 protocol, has low power consumption of 40mA@3.3V (max), an antenna on board, and -162dBm tracking sensitivity. With 56 channels in search mode and 22 channels &#8220;all-in-view&#8221; tracking, the GP-20U7 is quite the work horse for its size.<\/p>\n<p>This one is unused and doesnt have a conection TX pin.<\/p>\n<p><strong>NMEA V3.01 Protocol<\/strong><\/p>\n<ul>\n<li><strong>Its output signal level is TTL:<\/strong> 9600bps (default), 8 bit data, 1 stop bit and no parity<\/li>\n<li>It supports the following NMEA-0183<\/li>\n<li><strong>Messages:<\/strong> GGA, GLL, GSA, GSV, RMC and VTG<\/li>\n<\/ul>\n<p><strong>NMEA-0183 Output Messages<\/strong><\/p>\n<ul>\n<li><strong>NMEA:<\/strong> Record Description<\/li>\n<li><strong>GGA:<\/strong> Global positoning system fixed data<\/li>\n<li><strong>GLL:<\/strong> Geogrphic position \u2013 latitude \/ longitude<\/li>\n<li><strong>GSA:<\/strong> GNSS DOP and active satellites<\/li>\n<li><strong>GSV:<\/strong> GNSS satellites in view<\/li>\n<li><strong>RMC:<\/strong> Recommended minimum specific GNSS data<\/li>\n<li><strong>VTG:<\/strong> Course over ground and ground speed<\/li>\n<\/ul>\n<p><strong>DL2108Mk03<\/strong><\/p>\n<p>1 x SparkFun Thing Plus &#8211;
