[Radio] Long range radio link [Digi Xtend] (for Beagleboard)
Some time ago i fabricated 10 custom PCB breakouts for the Digi Xtend 900 MHz 1Watt radio transmitter. They are simple breakouts on which you can mount the Xtend module, and give it a USB connector and some nice lights to see what the thing is doing. I have used these boards to give the Beagleboard a long range wireless radio link. Sadly though, these Xtend module’s are not really permitted in Holland (900Mhz, 1Watt), so I decided not to use them. But still, maybe someone from America or Australia can still use my design. The breakout that the Digi company offers is around 300E, while my module costs around 8$ with all the parts. I still have some PCB’s left, so if you want them i can send you one if you pay for the mail.

If you are interested in more ‘breakouts’ or ‘shields’ like this radio one; or if you have a Beagleboard (on which this module mounts exactly) you might want to check out my other post in which i have made a battery-board and a GPS/GPRS board.
