Okay, the completed board has been sitting around my apartment for way too long, and it's about time I got it all hooked up. I'm not quite clear on the last few details re: hooking up the power, though. As was suggested, I've got a Meanwell RS-25-5 and an AC plug/switch assembly. It's obvious that + and - on the SBC should go to V+/V- on the PSU, but it's not very clear which of the holes for the power plug V+ and V- are. Moreover, is one of them a separate ground? Does that need to be connected to the ground line on the PSU, or does the ground line on the PSU go to the ground blade on the AC plug?
Also, is there a good simple hack that could be done to add a simple timer interrupt to the system? I've been toying with the idea of building this into a homebrew MIDI sequencer/workstation, but that would require a reliable clock source...
