Ideal diode to prevent reverse
polarity at the input
+5v @ 3A PSU ( 7.5v-28v Input )
5v @ 3A PSU
4 pin Power connector
as found on Floppy drives
+12v is only needed for PCIe and the FAN. If these aren't used then +12v isn't needed
Can be used to power the CM4IO board. NB +12v will also be available at the DC Jack
Can be used to power other devices if total loading on PSUs aren't exceeded
