This article describes a 32-bit bus card bus pinout discussion. The circuit  is very simple but effective utility, worth Duokanjibian then master the principles of this principle. Card Bus card using proven PC card form factor. There are different types of plug-in bus card (size TxLxW):
First class: 3.3 mm × 85.6mm × 54.0 mm
Type II: 5.0 mm × 85.6 mm× 54.0 mm
Type III: 10.5 mm × 85.6mm × 54.0 mm
Card bus provides a 32-bit multiplexed address / data path, working on PCI local bus speeds up to 33 MHz, generate a peak bandwidth of 132 mb / sec. CardBus is achieved by using a synchronous transfer direction explosion bus standard, and a bus protocol, which is essentially the same as a bus standard.
