It's quite complicated. I have a Hitachi-LG DL10N disc drive out of an xbox 360 slim, which I want to connect to my RPI. The disc drive has a somewhat unique 12-pin power connection cable. since I can't find a converter cable that converts this unit to usb, I am making my own converter using a breadboard, jumper wires and the RPI's GPIO pins. Below a picture of the pinout, which I am basing this on. (I am using the female connector)Maybe.
It depends on what the device is, how much current it draws and what other connections it has to the RasPi board.
As you can see, pin 8 (of the female connector) uses +5 volt. But, I read, that you must reduce the 5 volt down to the 3.3 volt the drive needs. So I was wondering if you just can connect it directly to the +3.3 volt RPI pin, instead of connecting it to a +5 volt pin and reducing it down to 3.3 volt on the breadboard, using resistors or something.
For the drive's 12 volt needs, I am using a external power source, also connected with each other on the breadboard.
Furthermore it has no connections, other than that pin 4 of the female connector is connected to a GPIO pin on the RPI, so with a simple code I can change the HIGH/LOW status of that pin to, hopefully, control the disc drive to open or close.
Please let me know if I have made any mistakes, I haven't tested this build yet.
