The new Raspberry Pi 2 came out with much fanfare. Up until now, finding a low cost desktop-class embedded PC was difficult. The original Raspberry Pi 1 Model B had a followup B+ model that did add some improvements, but this Raspberry Pi 2 Model B is significantly faster. Six times faster!
Oh, and it’s cheap. Yes, $35 for a quad-processor embedded computer with HDMI, audio, USB ports, etc.
The vastly improved processing power makes this a perfect small form factor hobby PC for radio enthusiasts. Previously, it was very difficult to decode things with SDR software on the Pi given the limit horsepower.
