5.4.3 Atmel JTAGICE3 Target Connectors Part Numbers
In order to connect the JTAGICE3 50-mil IDC cable directly to a target board, any standard 50-mil 10-pin header should suffice. It is advised to use keyed headers to ensure correct orientation when connecting to the target, such as those used on the adapter board included with the kit.
The part number for this header is: FTSH-105-01-L-DV-K-A-P from SAMTEC.
