Do check the max input voltage, but both are OK with 12V.<br /><br />I hope this helps.SteveDeehttps://www.blogger.com/profile/10645378028590228663noreply@blogger.comtag:blogger.com,1999:blog-8042569099194536366.post-21451361997244544782017-01-27T13:51:13.257+00:002017-01-27T13:51:13.257+00:00Could you give a link to the 78B5.0 voltage regula...Could you give a link to the 78B5.0 voltage regulator that you used please?<br />I've been attempting to figure out how to combine both 12v and 5 feeds to power pi (5v) and LED array (12v). <br />Incoming voltage is either 48v (this is what comes down poe), or 12v (stepped down from poe).<br />I have tried one of those step down 'buck' things to drop down from 48v to which I broke :(. Your solution seem to be a lot neater & compact.NestBoxTechhttps://www.blogger.com/profile/17596961979586589583noreply@blogger.com
