We're thinking about putting our custom hardware on a CF or PCMCIA card and using your CF bus driver to access it. Do you have any suggestions for connectors to use?

Sounds interesting! Make sure you have a good grasp of the PCMCIA and/or CF standards if you're going to make a generic card. There are significant mechanical, electrical and logical standards to follow. One common hurdle is the tuple information that your card needs to be able to provide to identify itself to the host system. However, if you're just going to use your hardware on systems that already know to expect your card in the PCMCIA/CF slot, you can eliminate that requirement.

But I think you're asking about the connectors themselves.

PCMCIA and Compact Flash use 0.050 x 0.050 inch headers. You can use a variety of receptacles of the same size from manufacturers including Molex, Samtec, JAE and Amp. To create a CF or PCMCIA card, you'll need to use a straddle-mount connector that slides over both ends of your PWB.

Molex makes kits for Type II PCMCIA and Type I Compact flash cards. You can find them at http://www.molex.com -> Memory Card -> Compact Flash or PCMCIA. There are a variety of PCMCIA kit starting with p/n 67049; the CF kit is p/n 67045.

FCI also makes a CF card kit("Industry Standard -> CFA"), but they seem to be obsoleting the receptacle. Part numbers are 73279-003 (50 position CF Receptacle), 62195-002,-003 (CF upper cover), 62197-001,-003 (CF lower cover).
