From reading the "getting started with the xmega on the stk600" pdf, the following is stated:
The routing card used for ATxmega128A1 is "STK600 "“ RC100X- 13" and the socket
card used for 100 pin devices is "STK600 "“ TQFP100"
What I'd like to know is, is the RC100X-13 card included when you buy the TQFP100 socket board ? I can't find it at as a separate part at farnell, alltough there are quite a few different routing cards listed there (Xmega A3 and A4 have separate routing cards listed).
