Modified Echo Version 1 - Complete But Broken

This version milled out a bit hairy. Some of the traces were broken, so I used jumpers to re-connect them.

There must have been a short somewhere - after stuffing it, setting the fuses and flashing it, I plugged it in to a 9v battery and received a puff of smoke for my efforts. The LED went on - then smoke came out.

In addition, I placed the button too close to the programming header, making it hard to press the button. I am not including the Eagle board or schematic here - see version 2 for a better board.

Back to Eagle!!! See version 2 for a (hopefully) improved and working board).
