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 (9600 encode in development). Since the decoding is not hardware based, new demodulation capabilities will be added to existing TinyTrak4s.
  • APRS Digipeating - The TinyTrak4 can act as a smart APRS digipeater supporting WIDEn-N, callsign substitution, and dupe checking.
  • KISS TNC - Connect to a computer and operate standard packet, Winlink, and any of the APRS software.
  • APRS Messaging - Send and receive APRS messages with the optional display and keyboard.
  • Analog & Digital Telemetry - TinyTrak4 can read temperature, battery voltage, and other analog and digital sources.
  • 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.

Additional Functionality:
  • APRS tracker that can plot positions as waypoints on compatible GPS receivers
  • Weather station support
  • Packet display
  • Remote control
  • UI TNC
  • New! Send and receive APRS text messages with the AvMap Geosat 5. Get the latest AvMap firmware HERE. See Don's Video Demo

Note: There are currently 2 different microprocessors used by TinyTrak4 boards, and each requires a different version of the firmware. Built and tested TinyTrak4s sold after June 2010 use a MEGA1284P chip. All others, including current kits, use a MEGA644P. The chip type is printed on the top of the chip on the circuit board. The bootloader version can also be used to identify the chip. The MEGA644P uses bootloader version 1.2b, and the MEGA1284P uses version 1.2c. All TinyTrak4 firmware published after July 2010 will include versions for both chips, one marked 644 and the other marked 1284. Only the firmware version that matches the chip on the TinyTrak4 should be loaded.

TinyTrak4s are shipped with Alpha v0.67 firmware installed.
