It turns out that in the Wolfson Audio Card the external connection pins are significantly thinner then in other popular boards, like Arduino. The pitch (spacing between the pins) is also smaller.
In order to connect the Wolfson card to other board I would use the widespread jumper wires, but it turns to be impossible due to reasons mentioned above.
Is this problem known to community? What to do? Do more appropriate wires exist for this case?
Thanks and regards,
A quick Google got these:
I'm sure others exist, measure the header (pin pitch is the usual identifier but pin size is worth checking too) and do some Googling.
I can't suggest a part to use because you don't give any measurements for the connector on your board.
