Byonics TinyTrak3+
TinyTrak3Plus is an APRSTM GPS position encoder which, when connected to a serial GPS and a radio, will transmit its location at an adjustable rate. TinyTrak3Plus is the fourth generation in TinyTrak series, and is available as a kit construction project, or as a built and tested unit, providing an inexpensive way to build a mobile tracker without the need for a full TNC. It is configured by connecting to a computer's serial port, and running a simple configuration tool which allows setting of all user options. After that, the computer can be disconnected, and a GPS connected in its place for operation.

TinyTrak3Plus has the following features:
  • Decodes any NMEA-0183 compatible serial GPS sending $GPRMC or $GPGGA sentences. USB only GPSs will not work.
  • Can provide 5V power to an external GPS (such as the Byonics GPS4 or GPS5).
  • Transmits position, altitude, speed, heading, and timestamp (hour/minute/seconds or day/hour/minute).
  • Supports SmartBeaconing, which adjusts transmission rates to speed and turning.
  • Can transmit position in MIC-E, NMEA, or APRS ASCII text format.
  • Two configurations, with all user options switchable.
  • Burst after voice / Send Position Now input.
  • Handles position resolution down to 7 inches.

Also consider: TinyTrak SMT, the surface mount version of TinyTrak3, and TinyTrak4, with the ability to encode and decode packets.
TinyTrak3Plus User's Manual and Windows Configuration Software is available.

GPS WARNING: The Byonics GPS above is a 5 volt GPS receiver. Do not connect directly to 12 volts or it will be destroyed. If buying with a TinyTrak3Plus kit, configure J7 for 5 volts (the bottom two square pads soldered together). If buying with a TinyTrak3Plus built and tested, this will already be done for you. Do not use these GPS receivers directly with the older TinyTrak3 (non-Plus version).
RF Related Resets: If you see the TinyTrak3 yellow and green LEDs flash 3 times together, followed by a quick flash of the red PTT LED, and then it repeats, this is usually a sign of the TinyTrak3 resetting due to too much local RF energy. Solutions to this problem are lower RF power, moving the antenna further away, and/or toroid clmap filters on the cables leading to the TT3. One other possible cause is a low battery, or a short in the radio cable.

Add To Cart TT USB Cable - $20. This USB cable will connect a TinyTrak3Plus or TinyTrak4 to a computer USB port for configuring. In addition, if the TinyTrak is set for 5V on J7 (TT3+) or JP6 (TT4) to power a GPS, this cable will also power the TinyTrak from the computer. It is a USB A to DB-9 female, and is basically a USB to serial adapter plus a F-F null modem cable, with the bonus of providing 5V to power the TinyTrak via pin 4. Drivers can be found HERE. Not compatible with Windows 8.

A Gender Changer and a Null Modem Adapter, or the TT USB cable above, is needed to connect a TinyTrak3Plus to the computer for configuration.

Add To Cart TinyTrak3 Chip - $18. This is a replacement TinyTrak3/TinyTrak3Plus chip. Also, with this chip, a TinyTrakII can be upgraded to all the functionality of a TinyTrak3.
