Power In Interface

The PC/104 interface requires +12/5V power and is provided by the Power In header (J18). Though not

recommended for use when the PC/104 add-on board is powered directly, the Power In header supplies the

voltages shown in Table 3-7 directly to the PC/104 connector.

Table 3-7 describes the Power In Interface, which consists of a 10-pin, right-angle, header with two rows,

odd/even (1, 2) pin sequence, and 0.100" (2.54mm) pitch.

Note: The shaded area denotes power or ground.

Battery Interface

An external battery connection is provided through the J5 header for the SIO VBAT supply voltage. Pin 1 is

+3.3 volts power, and Pin 2 is Ground. See Figure 2-6 on page 10 for pin locations.
