3.17. Input Power Requirements
The EDM1-IMX6PLUS 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
Table 39 - Input Power Signals
Power Rail Nominal Input Input Range Maximum Input Ripple
VCC (18 pin) 5V +4.75V - +5.25V ±50 mV
5VSB (2 pin) 5VSB +4.75V - +5.25V ±50 mV
3.17.1. Power Management Signals
The EDM1-IMX6PLUS 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.
