Computer peripheral equipment manufacturers use CF-IDE cards in conjunction with CF cards to test motherboards, sound cards, graphics cards and other products. In these occasions, the power supply needs to be turned on/off frequently. Traditional mechanical hard drives are easily damaged. CF is a kind of electronic hard disk, which is completely different from mechanical hard disk in principle, and it is not easy to be damaged in these occasions | Portable instruments that use embedded X86 or RISC cores usually have IDE interfaces. If the CF card cannot be directly connected to these instruments, you can use this adapter to complete the transfer | Personal computers (PCs): These computers are usually x86 kernels, which are the main platforms used by the card. Some digital cameras have a CF card interface. You can access your picture data on a desktop computer through this card | Industrial PCs use this card and CF card together to store embedded operating systems such as embedded LINUX or WIN CE | Support CF-I and CF-II two types of cards: also support IBM micro hard disk with CF-II interface. 5.0V or 3.3V power supply: select the appropriate power supply voltage according to your CF card
