ptFlex with DRA, Assembled

The ptFlex is a second-generation APRS tracking system, designed for high altitude ballooning, and other applications where size, power considerations, and interoperability is important.  The ptFlex with DRA includes a 500mW transmitter module frequency agile across the entire 2m band.

Included with the ptFlex:

• Integrated UBlox GPS module and antenna
• BMP-180 temperature sensor and barometric pressure sensor
• 500mW transmitter module, frequency agile from 144.000MHz to 148.000MHz.
• Battery voltage sensing
• Piezo element for audio annunciation
• Qwiic connector to interface with other I2C sensors.

There are only a few extra components needed to put the tracking system on the air.  These are:

• 5V TTL-level serial cable for configuring the settings
• ptConfiguration tool (a free download)
• A battery pack with a 2.1mm barrel connector capable of 7-12VDC (a two-cell Lipo battery works perfectly)
• An antenna tuned to operate at in the 2 meter band.

For more information about the ArduinoTrack system, see the Project: Traveler project page and read the ArduinoTrack Instruction Manual.

Note: A valid amateur radio (Ham) radio licensed is required for operation of this tracker.
