Cost savings, probably.Every few cents count, you know
Well Rick, if for real is only this the problem i disagree with this policy.
i paid € 0.50 for n1 7805 regulator voltage. (probably for 100 pieces could be cheaper)
this cost is really ridiculous when compared to the total cost of the entire board- and i must say it is very very important important for the security of the card.
is there a commercial power supply that has always the correct voltage ?
I have lot of power supply in my drawer that claim on the label to be 5V but, when measured by the tester, this one release 6v or 7v or even 10s in some cases.
There are power supplies that can have 5.30ve is already too much for nanoPEB.
so the risk is that you can connect a 5V powersupply and burn the nanoPEB, maybe not immediately perhaps in days.
I currently have 5 cards on a shelf between nanoPEB and CF7 not working.
Custodio Malilong confirmed me that they were probably wrong power supplies used on these cards... I measured the power supplies and are all between 5.16v and 5.30v ...
if there was a 7805 on the card nothing of this problem could be present. also all PEB cards have voltage regulators on them.
so, no i had about $300 of cards broken because decided to not use a 0.50 cent regulator
of course, my old CF7+ with voltage regulator still working good... the broken ones are all the without regulators voltage.
