= Power, system boot and resets =
This part can be helpful to power up and power down the full system correctly.
== Power sources ==
=== Input Power sources ===
*'''VIN''' is the main voltage regulator that generates all the necessary internal voltages for to IGEP COM AQUILA. VIN source needs 5V and 400 mA (typical value), read the design rules to determine the maximum current load applied.
*'''VBACKUP''' is RTC backup power supplyused to keep alive the hardware clock.
=== Output Power sources ===
*'''VOUT''' is a linear regulator that supply offers 3V3 / and 1A
*'''VREFP_ADC''' is a supply voltage range used for ADCanalog digital converters.
=== Power sources design rules ===
* IGEP COM AQUILA uses a TPS73701, this LDO converts 5V (VIN input) to 3V3 (VOUT output), so you can use the following formula to calculate the maximum VIN current consumption: Ivin (maximum supply current) = 550 mA (IGEP COM AQUILA Internal maximum current) + Ivout (maximum output current).
* Read the resources detailed above to get more information.
