Here is the shipping email confirmation from Zefir.  I already offered to make contact with anybody who is interested so please don't assume you know who I am, whoever that maybe.

I will offer them at $50/chip for whoever is interested.  Same day shipping.  Send me a PM and I can give you a call.

And no I would not recommend using that board design.  The opensource one from Bitmine.ch on github is suitable.

That is true, but that was just the going rate for the chips.  But it still could be a good price for those already with some hardware for the A1 chip. 

And it is OBO so I am open to any offers.

Is it good enough price for you?   

Hello all,

After a few failed attempts I have decided to liquidate my remaining bitmine A1 25 GH/s chips.  This endeavor ended up taking to much of our time and we made the choice to move on.  To those with working boards or under development this could be a great way to get a few extra mining chips fast.

So we have 35 untouched bitmine chips  These were purchased from Zefir a few months back.  At $3.5 per GH we are asking $3050 for them or OBO.  It would ship same day payment is received.  If you are local to the United States I would ship them overnight.  We also have 15 chips that were soldered on at one point, but have since been removed.  They didn't receive voltage spikes, it was mainly just bad board design.  Given the condition and buyer beware on these 15, if you are interested we could give them to you for $2 per GH so $750.

If anyone is interested please reply and we can set up payment details.  If you in the United States I can give you a call for verification and peace of mind.

Here's the chips:

Thanks All.

I use Mouser for those.  Digikey doesn't stock them as well.  Part number 45558-0003.  Also the upright connectors in the BOM don't match the pitch I measured in the gerbers, so the part is completely wrong.  The pitch does match the part number above though.

Just checked looks like Mouser has upright connector with correct pitch as well.  45718-0002

Mines on my way!  I examined the gerber files pretty thoroughly and couldn't find any errors.  Have you ran into any issues with the design itself?

On the BOM I selected an alum cap, P15077CT-ND, for C500, C501...  Obviously they didn't mean to use an LDO converter and I don't think they meant an axial cap either.  I think was the biggest misprint.  Also, I have plenty of right angle pci-e power connectors and plan on soldering them on the underside of the board(backwardz) so polarization is still correct.  I couldn't seem to find the upright ones.

Could you send me yours.  I'm curious what components you ended up selecting.

I believe he was saying he didn't have any extra chips.  A single chip design should function just fine.

Does anyone happen to know if the reset line needs to be pulled high.  It wasn't specified, but most resets are.  I plan on connecting all the reset lines to a bus to a Uc through a level converter.
