Interfaces
This chapter provides the pin signals for all the non-standard user interfaces on the Q7-BASE.
Unless pinouts for industry standard interfaces have been modified, those pinout tables will not
appear in this manual. Signal definitions for standard interfaces such as SATA, USB, and PCIe
connectors can be found in their respective specification data sheets.
3.1
ATX Power (CN1)
Table 3-1 lists the signals of the standard ATX Power connector, which provides 24 pins, 2 rows,
consecutive pin sequence (1, 13) with 4.20mm pitch. Use the SW3 button switch on the carrier
to apply power to the module.
NOTE: Shaded table cells denote power or ground. The # symbol indicates the signal is Active
Low.
The tables in this section define pin sequence
using the method in the following example: A 10-
pin header with two rows of pins, using odd/even
numbering, where pin 2 is directly across from pin
1, is noted as
10 pins, 2 rows, odd/even pin
sequence (1, 2)
. Consecutive numbering is
noted, for example, as
24 pins, 2 rows, consecu-
tive pin sequence (1, 13)
, where pin 13 is directly
across from pin 1. Refer to Figure 2-1 for pin-1
locations.
