Hi.

Im currently building a embedded PC-System with a PCMCIA reader from
AAEON (PCM3115-B)

Up till now it worked fine with all PCMCIA cards that I have tried.
But when I try to use a WLAN card from 3COM (3CRSHPW196) it won't fit
in the PCMCIA reader.

One of the corners on the card are to thick to fit in the reader.

The only differens from this card and the other cards that fit are
that the 3COM card i a 3,3V card. The others are 5V cards.

I've failed to find any info on if there are physical differenses
between 3,3V and 5V cards. (Even 3COM didn't know)

Any of you guys knows?

Thanks

/Stefan

Yes, there are differences. They are "keyed" differently, to prevent
insertion of a 3.3V card into a socket that only supports 5V.
