TinyTrak4
TinyTrak4 takes the features of the popular Byonics TinyTrak3Plus and adds...
  • DSP Packet Decoding - Using software DSP, the TinyTrak4 can not only decode 1200 baud packet, but also 9600 baud, and 300 baud packet, DTMF, and more. Since the decoding is not hardware based, new demodulation capabilities can be added to existing TinyTrak4s.
  • Field Upgradeability - New firmware can be downloaded for free from the TinyTrak4 website and sent to the TinyTrak4 with a computer serial port and a F-F null modem adapter.
  • Analog & Digital Telemetry - TinyTrak4 can read temperature, battery voltage, and other analog and digital sources.
  • More powerful processor - TinyTrak4 has more processor speed, code space, RAM, and EEPROM than the TinyTrak3 to allow for more features.

Implemented Functionality:
  • Field upgradeability
  • TinyTrak3 features - Most all the TinyTrak3 functions have been translated to the TinyTrak4
  • KISS TNC
  • UI TNC
  • APRS tracker that can plot positions as waypoints on compatible GPS receivers
  • Telemetry
  • Smart Digipeater
  • Packet display

Planned Functionality:
  • 9600 baud and 300 baud encode and decode TNC & Tracker
  • DTMF encode and decode - use for remote control, logging, transmitter hunting
  • Weather station support
  • PSK31 support
  • Remote control
  • Full TNC
Ordering

Please note that while TinyTrak4 has been successfully used by hundreds of operators, it still does not contain all planned functionality. New code will be written and posted to this site, and that code can always be downloaded for free from this site to upgrade existing TinyTrak4s in the field. If you are concerned about ordering a TinyTrak4 before a feature you need has been added, please delay your purchase and contact Byonics by email.

Note: The TinyTrak4 is usually shipped with a diagnostic firmware loaded. To use the TinyTrak4, the desired firmware (APRS tracker, KISS TNC, Alpha, etc) must be loaded first. Please see the firmware manual for instructions on how to do this.

TinyTrak4 Built and Tested with Case - For those not interested in soldering together the kit.
