Standard IDE interface interface: true-IDE mode, and supports DMA-66 transfer mode. Support CF-I and CF-II two types of cards: also support -hard disk with CF-II interface. The IDE interface is a 40-pin/2.54mm female connector: this card can be directly inserted into the IDE socket. With LED indicator: ( LED), CF access ( LED), whether the card is inserted (card detect LED). Master/slave jumper: it can be configured as master or slave. the CF card as a : automatically supply from the IDE's 20-pin or external floppy drive socket. 5.0V or 3.3V supply: select the appropriate supply voltage according to your CF card. In these occasions, the supply needs to be turned on/off frequently. mechanical hard drives are easily . CF is a kind of electronic hard disk, in principle, it is the as mechanical hard disk Portable instruments embedded X86 or RISC cores usually have IDE interfaces. If the CF card cannot be directly connected to these instruments, you can this adapter to complete the transfer. Name: Riser Card : MCA0-02 The Compact Flash (CF) card is a removable solid-state electronic disk with a standard IDE interface interface. CF card is a low-cost electronic disk card, which is widely used in notebook computers, personal digital assistants (PDA), portable or industrial equipment. In electronics factories, people CF cards as -hard drives to store test software, because it is very difficult to turn on/off the computer frequently. It is easy to damage the mechanical hard disk. Colour: green Material: PCB Package Contents: 2 * Riser card Only the above package content, other products are not included. Note: Light and different displays may the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
