Are any smaller quantities of the chips available ie 30-100? id like to get some if they are.
January 17, 2014, 11:02:18 PM
Any status updates from people using these chips?

thanks Bestlymac,
The BOM and open sourced documents will be uploaded in two days.
All the file needed for a antminer S1 design will be uploaded.
Is there more detailed information about the chip's inner
workings available? So custom designs can be made?

When you get all the info you need I hope you will create a nice easy USB design

I did not see a document containing the chip protocol. Is it available?

@Bitmain: Is there a board design competition and would we get samples if there is a competition?
December 17, 2013, 09:27:08 AM
Bitmain i have sent you a email and am awaiting a response so we can get our group buy moving forward.
Thanks
Don't hesitate to layout and prepare the sample PCB, if you have already preview our documents. Thanks
All the documents will be uploaded to our github soon.
December 17, 2013, 02:12:23 AM
Sounds great. I just need the remaining info so the fabricator can give us a complete quote.

You probably want to make it modular so you can sell different speeds.
My concern with investing much in this chip is that it's not nearly as productive as the others coming out and less productive than others already out. The price is write and it may be useful for USB's.
How does the electrical efficiency compare with BitFury? Is it more productive per amp, or whatever.

or you can scale it down to avalon blade design and still get a decent miner with 4 modules that would hash at 360...
900 GH/s miner is a lot of chips.
Would be around 320 chips. December 16, 2013, 02:28:23 AM

Any idea about prices yet?
Yes we do have but this is currently internal use only and is only a rough idea based on estimates of the Wasp and Hive but only the schematics and BOM for the Wasp are done.
So we are unable to give a prototype cost breakdown as the Hive is still being worked on. Production would be January at the earliest and our plan is not to do pre-sales so it will be pop-up sales. Soon as there is stock they will go on sale and if we run out sales stop.
So pricing will be posted before New Year at the earliest I would think and set by the reseller, diy makers, the WPC if we do a larger production run or other fabricators who are licensed with us to produce the BM1380 Wasp. Prices probably will vary.

Agreed; the datasheet will need a little more detail for us DIYers. December 15, 2013, 10:27:21 AM

Bitmain, i send you a PM about the chips, can you please take 2 minute and answer? Thanks and PM answered. Updated with a newly added policy, Paying extra 10% can accelerate the lead time to 4 weeks. We have already made the documents we think is completed for building a miner with our chip. We will send to some community member to review for two or three days, and we can know whether there is something that will make other EE confused or hard to understand. Then we release all the documents to the public. make sure to send to burnin. he does good boards. Any thoughts of making rackminers? like U3 size but 500GH++. price est?

beastly when do you plan to open the sales? hopefully no preorder... It will be part of the assembly service available to the chip group buy members.  We are considering building rack miners with bit main chips. They would be roughly 900Gh/s December 11, 2013, 06:10:56 AM

Hmm Because it is not open source dude. your business model is not much different than Asic one.awfull pricing comparing my project the wafer cost is 3k,with aprox 3k chips so their cost price is aprox 10k and noone is interested in participating in my 65 nm at cost price crazy folks You get the technology with our money invested we eventually get good praise from today point's of view and we are going probably to loose our investments from tomorrow point of view who said it s not opensource? i ve uploaded all the needed files for the pcb and else So you think he is going to give you access to gds and the mask? hmm please confirm with them as i would be interested also if this is the case 1. He invested own money or at least not collected from community 2. He does not claim that he is open source he is here for the businesses. No doubt about that 3. The magic word open source means nothing anymore Can I ask you if you claim to be open why you are not giving your mask and GDS and mask to the community I know do not answer it is NDA shit or you paid cheaper to cut the costs or million reasons which has nothing to do with opensource and most probably is a bulshit December 09, 2013, 11:51:51 AM

I am interested in getting in on this one. I don't need raw chips though.

I would be able to fund and run a batch of very nice looking miners, complete with plastic housing, manual, shiny box, CE and UL cert and so on. Am in Shanghai, possible to communicate in Chinese.
However I need somebody to do the PCB's reliably without fucking me over. Anybody interested contact me for details. Thank you. December 09, 2013, 06:11:32 AM

Summary BM1380 is a Bitcoin mining chip developed by Bitmain, a Chinese based IC company. We use the chip to build S1 Dual Blades, nearly a thousand of which has been sold to the Bitcoin community. BM1380 can run at different mode, depending on the favorite of the users. It can run at 0.75V core voltage and 0.68J/GH high efficiency which can compete with some 28nm mining chips. At 0.75V the hashing board runs without a heat sink. BM1380 is also running at 1.1V or 1.25V voltage sounding reliably, doubling the hash rate and the efficiency spec still better than most of other 55nm node chips on the market. Now the chip is open for purchase. About the Chip Process Node: 55nm Number of Cores: 8 Package Type: QFN56 Packaged Chip Size: 8 mm x 8 mm Rated Hash Rate: 2.8GH/s @ 1.1V
