Question on PCB and routing

[Fivetide]

Oh so they're switching, not linear, regulators - disregard what I said about the power dissipation then as that's irrelevant. I'd still use some small capacitors though.

You're pushing your luck asking for 1.5A from a regulator rated for 1.0A.

Hi Jonathan, yes there are 2 regulators R-785 0-1.0 and R-78B5.0-1.5 the 1 amp is for the Raspi and the 1.5 is for the USB the 1.0 amp has 2 output 2 pin Molex’s, one powers the Pi itself and the other powers Independantly RC-servo controller board for Raspberry PI Version 3

Fair enough. They're both labelled as -1.0 on the PCB which was a bit misleading...

Do you really need the high efficiency from these switching regulators? As m_c hinted, you could save a lot of money by using linear regulators and adding heatinks.
