raspberry pi and a 'slice of pi' + xbee RF radio

I have some xbee radios from other projects and so I assembled the 'slice of pi' board and used the included xbee sockets. its all 3.3v so it just plugs and plays.

 

 

this gets connected to the internal uart, /dev/ttyAMA0. in fact, that's the default bootup console and so, if you connect another xbee to a computer, run a comm-term program (kermit, etc) you can see the bootup console messages across RF. I've been able to get from one end of the house, downstairs, to the upstairs corner. not too bad..

 

note the 'vga cooler' heatsink (blue) I added to the ethernet NIC chip.

 

power is via the 2 clip leads and comes from a decent lab supply. at peak, I see a full 1.0 amps being drawn at 5.1v.

 

oh, and this is the 1ghz overclocked config.
