The circuit uses an ATxmega256A3U microcontroller and it's UART modules to chatter over 5 ports. It includes a CP2102n USB - UART bridge, acting as the 6th port, to receive serial messages from a computer.
# Notes
- 0.1uF cap near CP2102n is too close, can't place
- silk port labels are under ports
- clkout has to be pin7 on C, E or D
