==Introduction==
About voltage range, three supported configurations are available. These configurations are indicated by the value of the '''f''' field of the ordering code. The generic ordering code is in the form:
*the same voltage rail is used to power AXEULite SOM and 3.3V carrier board circuitry.
Since powering is strictly related to reset signals, reading of [[Reset_scheme_Reset scheme (AXELULiteAXEL ULite)|this page]] is highly recommended.
Fot information about power consumption, please refer to [[Power_consumption_Power consumption (AXELULiteAXEL ULite)|this article]].
== Power Supply Unit (PSU) and recommended power-up sequence ==
Implementing correct power-up sequence for i.MX6UL processors is not a trivial task because several power rails are involved. AXELULite AXEL ULite SOM simplifies this task by embedding all the needed circuitry. The following picture shows a simplified block diagram of PSU/voltage monitoring circuitry:
