The DA104 provides a convenient means of integrating a 2.5" IDE hard drive, M-Systems CompactFlash, or M-Systems IDE2000 Flash Disk onto a PC/104 "stack". Connection of the drive to the host CPU IDE port is supported by a standard 40 pins ribbon cable. The 5VDC power for the drives is supplied either though the PC/104 bus, or 2 positions screw terminal. For additional memory, a second 2.5" hard drive or IDE2000 Flash Disk can be mounted to the underside of the module.
