4.2 I/O expansion headers
32159A-AVR-01/11
There are four available I/O expansion headers on the kit. Some pins have shared
functionality with onboard functionality. If “clean” expansion ports are needed, there
are available cut-straps on some of the ADC inputs to remove onboard functionality.

1. Standard pinout for JTAGICE mkII and other Atmel programming tools.
1. ADC channels can be disconnected from onboard functions by cutting the
to
available cut-straps on the bottom side of the board.
