What are the differences between CF type I , CF type II and CF I/O cards?
CompactFlash has three subdivisions of CF cards, Type I, the slightly thicker Type II cards and the I/O cards. CF Type I At 43mm (1.7″) x 36mm (1.4″) x 3.3mm (0.13″), the CF Type I card’s thickness is less than one-half of a current PCMCIA Type II card. It is actually one-fourth the volume of a PCMCIA card. Compared to a 68-pin PCMCIA card, a CF card has 50 pins but still conforms to ATA specs. It can be easily slipped into a passive 68-pin PCMCIA Type II to CF Type I adapter that fully meets PCMCIA electrical and mechanical interface specifications. CF Type II At 43mm (1.7″) x 36mm (1.4″) x 5.5mm (0.19″), the CF Type II card’s thickness is equal to that of a current PCMCIA Type II card. It is actually less than one-half the volume of a PCMCIA card. Compared to a 68-pin PCMCIA card, a CF card has 50 pins but still conforms to ATA specs. It can be easily slipped into a passive 68-pin PCMCIA Type II to CF Type II adapter that fully meets PCMCIA electrical and mechanical interface specifi
