=== Input Power sources ===
*'''VIN''' is the main source voltage regulator that generates all the necessary internal voltages to IGEP COM AQUILA. VIN source needs 5V, read the design rules to determine the maximum current load applied.
*'''VBACKUP''' is RTC backup power supply used to keep alive the hardware clock.
=== Output Power sources ===
*'''VOUT''' is a linear regulator output source that offers 3V3 and 1A.
*'''VREFP_ADC''' is a supply voltage used for AM335x analog 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 internal maximum supply current) + Ivout (Vout maximum output currentused).* Read the resources detailed above to get more More informationat [{{#lst:Template:Links|IGEP_AQUILA_EXPANSION_ISEE_Hardware}} IGEP AQUILA EXPANSION Hardware Reference Manual] section 6.1
