Wow never seen one that bad. This is why I stress to always check your connectors once in a while to see if they are hot, and to never run off one plug if your using a third party PSU.

You can use the other connector, but I would not run it past eco mode otherwise you risk doing the same thing to that plug.

New to mining...been reading and watching videos...love this stuff and can't wait to try it out. I just bought a FutureBit Apollo. Trying to figure out what power supply to buy. I'm looking for a standalone unit to just plug into a wall outlet and then connect to the Apollo. Any help is appreciated! Thank you

jstefanop would really need to come up with some strange implementation in order to block such possibility.

The blockchain is just a collection of files in some directory. Since access to the mcu and its filesystem isn't blocked, reallocating a directory to a connected external disk will be possible even if such option doesn't get implemented in the user interface. I don't however think that having the blockchain on the sd card could cause an issue with card wear as the blockchain progresses with a clear pattern instead of random writes. Random reads on the other hand don't really matter as long as the read performance of the sd card doesn't become the bottleneck. The benefit on having the blockchain on an external drive (or usb stick) would be to keep the option making the Apollo software upgrade with full sd card overwrite without having to start from scratch with the blockchain.

No, any future updates will increase the reliability of mining, and probably some voltage/efficiency gains but hash speed will remain between 100-140 MH/s. Im focused on brining the big functionality updates like full node/wallet functions etc.

Thanks whiteogre! - pretty much what I thought. I have purchased 2 so far and still learning about crypto stuff. I know efforts, as mentioned by jstefanop, to bring full node to Apollo. I understand what that means but not sure how that would impact mining. For example, it seems like less network latency time would be realized so there should be less stale shares. Just guessing.

I did put a usb fan in front of each which helps as they purr perfectly in balance mode.

Yea thats the same type of SDXC UHS card as the 64 I tested, so I guess anything past 64 wont work. If anyone else has other 128GB or larger cards they can test let me know.

Either way 64 is more than enough when we release the full node/lightning update.

One of my units experienced temperature cut-out I think.
It was hot to touch and not mining, miner offline and fan not spinning. This is a second time this happened. I power it off, after few minutes plugged back in, it started mining just fine. I am running Eco mode with Auto fan.

I really think we need to get Minimum fan speed option on Auto mode, so temperature is controlled in more stable way.

For now, I changed fans in both units to manual mode at 15%. It's still quiet and stable. Temperatures are 52-52 C instead of 70 C in Auto mode.
