My Orange Pi power supply project

[Moondeck]

Hi everyone,
I made a little power supply for my Orange Pi to solve the problem of sourcing a high-current 5V supply and small barrel jacks used on the OPi.
I have published it on my little blog-site-thingo that i actually run on an OPi PC+ with that very supply
Please, tell me what you think about it and what i should improve. I am also soon coming out with a new version, with some minor adjustments and i am going to produce a few, would anyone be interested in getting some?

Thanks,

Neat project!

A few suggestions:
Neither your blog nor your post mention the input voltage of your converter. Is it meant to be powered by 12V? Is it meant to be powered from a Li-Ion battery? Who knows ...

How about cooling? These things get hot very quickly, and now your covering the top with your converter. Maybe make the board as narrow as possible, or add a cut-out over the CPU where a heat sink can poke through.

keep going, Werner

For some reason I cannot seem to access the url.
Is it me locally or do others experience similar issue?

Sorry for my late reply, i was busy with stuff.

Yes, its meant to be powered by 12V. You can use up to 40V if you increase the voltage/remove the input cap. Its a buck converter, so under-7V batteries are a no-go. I will mention it in the next post.

I've actually ran cpuburn for 24h with this supply on top and a little GPU RAM heatsink on the CPU, the cooling is enough. It was a major fear while designing but turned out to be fine.
