Almost all of the atmega pins are brought out to the 51pin connector.
Specifically, PortC, which is called PW for some reason, is completely
available if you don't use any add-on sensorboard. See my pinout list:
http://www.etantdonnes.com/Motes/ATMEGApins.txt
You can use my original email instructions for directly accessing
the controller pins. Or there is a T1 PortC byte access driver
buried in: http://www.etantdonnes.com/Motes/robocode.tar.gz
The issue is making physical connections. The MDA100 may be a break-
out board, I don't remember. You can find design for a simple BOB at:
http://www.etantdonnes.com/Motes/MicaBOB/
Unfortunately I don't have any to send you, or plans to make any more.
Hopefully you can follow the gist of it on your own.
