Appears to be something with the low-side FET. The damage is at the gate pin. Not sure what's up.
But if the buck is bouncing up to 1.1V, that's the point the ASIC will shunt it off to.
The low-side FET should never not conduct at all unless it's sorely damaged. Even if the gate doesn't kick the transistor on, the body diode would still conduct during the low swing of the switching. It'd run hot and not very efficient; I forget the Vf of the body diode but it's probably around 0.8V so if you were trying to crank 4W into the ASIC at 660mV that's six amps and a good 5W dissipated by the low-side FET with about 85% duty. The FET itself is rated much higher than that but this installation lacks the required PCB heatsinking to hold up. If the FET completely shot craps such that the switch and body diode aren't conducting at all, it's possible that the high-side could cause an overvolt condition.
I watch the current levels on every stick I test, and they're always in the same range (with about 5% variance) so it should have been working when it left my bench. But that doesn't always mean it'll work forever, unfortunately, and something could have gone wrong caused that transistor to drop out.
If you want to mail it back to me I'll send you a replacement. If you want I'll send it straightaway, or you mentioned ordering more and I can add one to that order when it's eventually placed.

I'm actually impressed, that make it super simple and super modular. How do you cut the plastic? With a wood saw? And where do you get those... "Egg Crates" for cheap? Then you just tie wrap the miner stuff and maybe hot glue or screw the plastic in place.
Right now i just put my stick on the hub and put it on the side so that the USB fan sticking out from the mobo blow air on it.
Egg crate is made of stiff polystyrene plastic, so it's easy to cut. I typically use diagonal cutters. The plastic easily splits along the cut line. Very easy to work with. Got the idea to use this stuff from a very different hobby (salt water aquariums). I bought a big panel a couple of years ago and have built out three small scale rigs out of the stuff. Usually I just tack down the power supplies, hubs, etc. with zip ties. Once the components are in place, the rig is effectively portable. It's typically used as paneling for lighting fixtures, especially comercial fluorescents, in the US at least. Any building supply or lighting company should have it for pretty cheap. If you search for "egg crate plastic" you'll find a ton of options.

How fast are you running those 2 compacs?

Thank you, this is great, i found this; http://www.homedepot.ca/product/egg-crate-white-louver-2375-inch-x-4775-inch/924867Its like 10$USD for 24*48inch~ thats a ton of material and its hella cheap. I'll have to pick some up next time i got the car. I will definitively use this as base from now own instead of the convoluted stuff i came up with for my GPU rig. And on top you can have air from go through. Great find! With this i might even be able to afix the Sidehack stick to my GPU rig that has a box fan blowing air between the GPUs. Wont need to use the USB Fan.

Very clean setup. I really like the plastic. I really wonder what a 3d printing master could do with plastic.
How fast are you running those 2 compacs?
Currently both of them are running at 306. That results in about 16.9 GH/s with 0.08% HW errors. I would have gone higher, but one of the units is a little weaker. I had to turn up the voltage proportionally more on the weak unit to get to 300-ish. I probably could mess around a bit more with the voltage and frequency to go higher. Or I could explore per-unit frequency options since one stick outperforms the other. Assuming that cgminer-gekko can in fact do that (I don't know). In the end it seemed good enough to get double the stock hash rate for the amount of fiddling I did.

lol, i didn't even check when it was posted, thought it was a few days back! don't take it the wrong way, I do have interest on failures like this, maybe that's the reason 90% of my miners are dead

Wont need to use the USB Fan. You're welcome. Post some picts when you've got your rig set up. The only downside of egg crate is that when you cut it, you can end up with a jagged edge. You can scrape yourself on it if you're not careful.

Sidehack, I appreciate you being willing to send one out under warranty. That's a standup decision and I hope people recognize such. I am going to PM you to confirm any RMA information, the ship to address, along with discussing ordering a couple more. The more I play with these bad boys and develope some of my more

Transaction fees go to the pools and the pools decide to pay them to the miners. Anything else, including off-chain solutions are stealing and not the way Bitcoin was intended to function. Make the block size set by the pool. Pool = miners and they get the choice.

Yes, the server where the files are, has been having some kind of trouble or they limited traffic. It did it to me the other day, just wait a little while and try again, eventually it will come back up and you can get the files. Or you can search around for another source server and add them to your /etc/apt/sources.list (I think that's it).

I did an sudo apt-get Update /fixed !  Beat me to it  For completeness sake though, when doing a new install on a Pi it's a good idea to go through the full upgrade process, like this: sudo apt-get update sudo apt-get upgrade sudo reboot
On a resource limited machine like a Pi this can take a really long time.

I did an sudo apt-get Update /fixed !  Well, I forgot about the sudo apt-get update, being done first  As long as you got a good powered hub (2.0 for the Pi's) you should be good to go. Here's 1 week running 5 stick's on a Pi-2 @ 175 freq. in balanced with 4 pools, so I think that's why the GF is 16, + the phone company has been working on the lines, which doesn't help, but still managed to get a best share of 197M (now all I need is ~65B share  ).

If you have trouble and cannot get to it try to use. Some have a power feedback - https://www.raspberrypi.org/forums/viewtopic.php?f=91&t=17560 . If you cannot get the hub to work try the compac directly on the pi and you can see if you have a hub problem. I was kinda a pain for me and my hub but I got it working after some reading.

Hmm, I don't fully understand the power requirements. I'm currently running this USB hub. http://www.oricoonline.us/goods.php?id=493712V 3A Does this mean I can run 4 sticks drawing 0.75A safely, or 2 sticks @ 1.5A each? What mhz would that be?
