5v @ 3A PSU

Can be used to power other devices if total loading on PSUs aren't exceeded

4 pin Power connector

as found on Floppy drives

+12v Input

2.1mm Tip +ve

+5v @ 3A PSU ( 7.5v-28v Input )

Can be used to power the CM4IO board. NB +12v will also be available at the DC Jack

+12v is only needed for PCIe and the FAN. If these aren't used then +12v isn't needed

Ideal diode to prevent reverse

polarity at the input
