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

It is a multi-functional front panel with 2 USB2.0 interface, one mic and one audio plug | You can use this device to directly convert the USB 9pin interface and audio on the board into 2 USB2.0 interfaces, headphone output and microphone interface, and install them in an idle floppy drive position. This provides a front USB interface and audio interface, Very convenient | Hardware requirements: a motherboard or adapter card with 9PIN interface and HD-AUDIO audio support, and a chassis with free floppy drive | Product size: floppy drive bit 102mm*25mm | Packing accessories: Floppy drive bit panel*1; DuPont line 9PIN-9PIN*1; Audio line 9PIN-9PIN*1; Fixing screw*5
