Yes i know, i mined the coins with S1's to buy the S2 on 16-03 for the second batch.
The S1's where great but this

I hope it's something i can solder back, that won't be any problem for me.
Even if it's a bga or something like that.
On the controller board are 5 led's, only one of them is green.
it's the led with R41D5 marking next to it.
Any thoughts?
look up support for the beaglebone black since that is the control module. its possible you need to swap in a new controller and/or sd card (probably <$50)
