Xilinx Evaluation Kits - 2-Pin External Access Headers - Which pin is pin 1?

Description


Some Xilinx Evaluation Kits feature 2-Pin External Access headers on the board, instance J16 on the Spartan-6 SP601 Evaluation Kit and J45 on the Spartan-6 SP605 Evaluation Kit.

If this is the case on the Evaluation Kit I am using, how do I identify Pin 1 of this header?

Solution

You can identify Pin 1 of this 2-pin external access header by looking at the underside of the board. If you turn the board over, you can find Pin 1 as it is identified by a square pad.

This rule of thumb also applies to all other headers on Xilinx Evaluation Boards.
