4.1.2 Daughter Card Standalone Power Input -External
A terminal power input is provided on the daughter card to enable use of the daughter card without
the motherboard.
When power is applied to the Daughter Card from Motherboard or External Terminal input or
PowerSBC with respective jumper selection, four green power LEDs adjacent to the terminal power
input connector (JP7) show the presence of the supply voltages as follows:
• LED D4 – Indicates that the 5.0 V linear regulator is enabled and working correctly
• LED D5 – Indicates that the 5.0 V switching regulator is enabled and working correctly
• LED D6 – Indicates that the 3.3 V switching regulator is enabled and working correctly
• LED D7 – Indicates that the 1.25 V switching regulator is enabled and working correctly
The connections of the JP7 power terminal are detailed in Figure 12 .
