The Raspberry Pi is paired with an RTL-SDR dongle for APRS iGate operations or wide band spectrum analyzer. The option with the TNC-Pi increases the capability when added with a transmit/recieve radio. Or you can setup the Pi to operate standalone on a Mesh Network. The high definition monitor, portable wireless keyboard, 5ah battery, and weather resistent case make this the ultimate portable Raspberry Pi setup.
This Raspberry Pi comes with a larger touch screen, longer battery cycle, and radio options
