Micro-Trak 300

The Micro-Trak 300 is a 2-meter transmitter combined with a TinyTrak3 controller chip that provides an easy and inexpensive way to build a small APRS tracker.

Just plug in a GPS receiver, such as the Byonics GPS2, add a SMA antenna, and start tracking!

The Micro-Trak 300 is available on either the North American APRS frequency of 144.39 MHz, transmits 300 mW and is sold as a built and tested unit. The PCB measures 1 inch X 3.3 inches.
  • No need to tie up an expensive radio for APRS tracking
  • No complicated radio cabling
  • Simple 2 wire GPS connection
  • Supports all the latest Byonics TinyTrak3 features.
