The Atmel JTAGICE3 probe has a 50-mil 10-pin JTAG connector accessible on the front of the tool's enclosure. The kit includes a 50-mil 10-pin cable, which can be used to connect directly to a 50-mil JTAG header on your target board. Should your target board be fitted with a 100-mil JTAG header (e.g.: Atmel STK®600), the 100-mil adapter provided (A08-0735-A) in the kit can be used. If your target board does not have a compliant 10-pin JTAG header in 50- or 100-mil, you can map to a custom pinout using the 10-pin "mini-squid" cable provided, which gives access to 10 individual 100-mil sockets.
