  • What kind of motherboard to use

    How do companies such as http://www.napdeck.com/ and others get the size of the mp3 player down to CD player size? They can't be using micro sized motherboard because even they are too large. Do they use proprietary, home-aid boards or what?

    they arent using motherboards at all. those are strictly MP3 players. you cant hook up a keyboard and start typing a letter. my guess is that they are using a decoder chip (similar to the one on the soundblaster live mp3+) to decode and play the mp3's.

      Well, they have to be using some sort of processor I would think to get the hard drive to be operational. I read the specs, but it didn't say anything about a processor.

        hoffa you right they are using some sort of microprocessing unit. I think most common one are the motorola ones ( dont remember the part number) But also to drive the IDE bus they need to have a IDE controller chip. But as most deck size mp3 players run on CDs so in this case they dont really need to have a IDE controller chip anymore. Which simplifies the design and of course makes it cheaper to make and program ... i guess this answers your question from last posting.

          I guess i wasnt too clear: a decoder chip IS a processor. it has the instructions on the chip on how to decode MP3's.
