Powering Pi3 and HDD

Post by Kenjutsu » Mon Oct 23, 2017 1:02 pm

Hello everyone

I need some advice. I want to power a Raspberry Pi3 and a SATA 2.5" HDD from a MeanWell NES-75-5.

My idea is to build a simple "breakout" board on vero board to take the output of the PSU and split it between 4 x USB type A connectors, and then power the Pi from one of these sockets. The HDD will be connected using a "Y cable" (for 1) a HDD enclosure, or 2) without an enclosure) with the data connector going to a USB port on the Pi, and the power connector going to a USB socket on my breakout board.

Can it be as simple as this or am I missing something? ;)
