EIDE Connector (CN10)
The EIDE connector is a 44-pin, 2 mm connector that can connect to a variety of EIDE or IDE devices. The
connector provides all signals and power needed to use a 2.5-inch form factor (laptop) hard drive. Also, the first
40 pins of the connector provide all of the signals needed to interface to a 3.5-inch or 5-inch form factor hard
drive, CD-ROM drive, or other EIDE device. The larger form factors use a 40-pin, 0.1 inch spacing connector, so
an adapter cable or adapter board is needed to connect to CN10.
