Sick RK3288 Q8

[scole of TSBT]

Comments on this PSU appreciated. It's a Mean Well RSP-320-5 psu. 5V 60A output, single rail but multiple connectors. 85% efficient, which is about the best I could find from Mean Well in that amp output range. More output than I currently need, but has room to grow. ~$60 US.

Looks really good :)

So here's the new PSU, a Mean Well RSP-320-5. Soldered eye connectors to a power cord bought at home improvement store. Made a 4 wire 22 AWG pigtail with female barrel connectors, soldered them into eye connectors. Put a male barrel connector on the android power cord. Getting a hair over 5V at the connector which plugs into the android. Just need to make two more pigtails to connect to the other 5V terminals and put barrel connectors on the other android power cords. Will make the other pigtails 5 wire.

Very nice! :)

Good job and so much neater than my wiring Scole!
You might have just shamed me into sorting out my 5 volt spaghetti shambles.

Thanks guys. Some of my projects don't turn out very neat. A big plus for doing this, other than replacing bad PSUs shutting down a systems, is the PSU is more efficient. It uses less electricity and generates less heat than the individual PSUs. I don't know how much electricity from the androids goes into heat (which must be cooled), but those single PSUs do get warm.

I made the rest of the pigtails and have all nine androids powered off the psu. It appears to give off no more heat than one of the individual psu's, so I'm happy about that. I appreciate everyone's input.

It is rediculous how inefficient the standard plug in PSU's are. Now your 5v cheap crunch power just got more ' green '

I tried and I tried but all three of my RK3288 androids are dead.

Have you tried a new SD-card or eMMC?
My Banana Pro is 'on the reserve bench' because it keeps trashing SD cards.
My Odroid-XU4 is not all that stable when pushed to the brink (2000 MHz) either, so I keep changing OS-es. Learning a lot from it actually.
My Cubieboard 4 is 'on the repair bench' ever since it went out with a BANG! -either board or PSU has blown -but I hope the SD-card....

If you want rock-stable ARM crunching, either choose BeagleBone Blacks (Argh! just one Cortex-A8 core) or Raspberries.
The Android64_9_PIE equipped Odroid-N2+ runs good till now too, I just had a 2nd in to be fitted out with 64-bit Linux.

If I were to try a Asus Tinker Board S with RK3288, it will go with a 52Pi Tower Cooler....
More or less the same for a BeagleBone AI, a reported hothead.

But serious: 5V-60A output? You may have fried the RK3288's...I guess 5V-3A is the most they need...
