When connected to a serial GPS and a radio, will transmit its location at an adjustable rate, providing an inexpensive way to build a mobile tracker. It is configured by connecting to a computer and running a simple Windows configuration tool which allows setting of all user options. Then the computer can be disconnected, and a GPS connected in its place for operation. The TinyTrak3Plus decodes any NMEA-0183 serial GPS sending $GPRMC or $GPGGA sentences. USB only GPSs will not work. It can provide 5V power to an external GPS, such at the Byonics GPS5, and transmits position, altitude, speed, heading, and timestamp. It also supports SmartBeaconing, which adjusts transmission rates to speed and turning and can transmit position in MIC-E, NMEA, or APRS ASCII text format. It supports two configurations, with all user options switchable. 73!
