用这种特殊的PC，整个SDR系统更加小巧。
Introduction
This is an experiment to see how well the RTL-SDR driver runs on a mid-range ARM SBC. The Beaglebone is an ARM-based single-board computer that's available for less than $100 yet provides a surprising number of powerful features. Since it has a USB host port and an ethernet port, it seems like a natural fit for a remote RF digitizer using the RTL-SDR driver and an inexpensive DVB-T dongle.
Getting it Going
You'll need the following materials and software •A Beaglebone - find them at various hardware vendors: ◦Special Computing
◦Adafruit
◦Digi-Key
•An RTL2832 DVB-T dongle (check ebay)
•A spare micro SD to install the Beaglebone OS
