3.17. Input Power Requirements
The EDM1-IMX6 is designed to be driven with a 5V input power rail.
The power domain pins have to be connected as follow:
•
All GND pins have to be connected to the carrier board ground pane.
•
All VCC pins should be connected to the +5V main power source.
If ATX functionality is desired the following power domains pin should also be connected (ATX mode
only):
•
All 5VSB pins should be connected to the +5VSB main power source.
•
EDM PIN#251 should be connected to the ATX power circuit PWGIN circuit

3.17.1. Power Management Signals
The EDM1-IMX6 has the following set of signals to control the system power states such as the power-on
and reset conditions. This enables the system designer to implement a fully ACPI compliant system
supporting system states. The minimum hardware requirements for an ACPI compliant system are an
EDM module supporting ACPI, ATX conforming power supply and a power button.
