Someone can give me dimensions of thermal pad? And what material is used (copper?).

Under development Modular UPGRADEABLE Miner (MUM). Looking for investors.
Changing one PCB with screwdriver and you have brand new miner in hand... Plug&Play, scalable from one module to thousands.

Is it still possible to obtain purchase of test chips?

Want to say thanks? 16ragydppe9QFRVhrdwEUjgfMS7KCfEFGY

First prototype of Bitfury S-HASH board is hashing:

Features:

16 Bitfury ASIC capacity
Adjustable (through 0805 SMT resistor) voltage regulator between 0.7 and 0.9V
Core voltage regulator has 50A capacity, so chips can be overclocked.
On-board ARM Cortex M3 processor with standard RJ-45 100 Mbps Ethernet port.
Built-in mining software can operate stand-alone. No PC or Raspberry PI needed, just an internet connection.
TCP/IP stack with DHCP and DNS support. Just fill in pool server name, port number, username and password.
Support for Stratum and backup mining pools.
Built-in small webserver for chip status/speed reports.
PCB temperature sensor, could be used for automatic shutdown when temperature gets too high.

If you don't have the budget for a large number of chips, overclocking is the best option, as it will get you 40GH/sec out of a card (probably more with better cooling), instead of 25GH for a standard H-CARD for the same 16 chips. At 40GH/sec, the card uses about 35 Watts, running off a standard 12V DC supply.

very nice. what kind of cooling are you using to get 40GH/s? what are your plans for this board?

Nice stuff indeed, congrats! When and where will we be able to order? Bitfurystrikesback.com?

Beautiful work cscape.

Is there any chance of retrofitting current H model boards for a little overclocking? I have no fear of a solder iron.

For cooling I have a standard PC case fan set up above the board, blowing down on the surface. No heat sink, so it's not an optimal set up. The board has a couple of mounting holes, and a flat back, so the idea is to mount a heat sink on the back.

No plans yet, just having fun. I will not be doing any manufacturing or retail selling myself, but I'm open for collaborations with other companies.

The voltage regulator on the H-CARD has a 30A capacity, which limits the overclocking range, and there are no simple replacements for the regulator.

Yesterday was my 27th birthday.... I'm just saying... Grin

I guess the orange tree my girlfriend gave me will have to do for this year hehe

It's beautiful cscape! So you are atm hashing at a steady 40GH/s without heatsinking? Nice!!
Looking forward for a manufacturer picking this up!

(Hmm... forum ate my reply. I'll edit this post and add it again).

Pretty much 40GH, yes. This is just a random sample of 16 chips, from what I suppose was the first batch of ASICs. There's some variation between them, and there's some fluctuations as I measure the hashing rate based on the count of valid nonces produced, and not the operating speed.

No, not at this moment. I'll first see if there's anybody interested in a commercial collaboration.

Also, mounting QFN48 chips with thermal pad and a few hundred 0402 parts is not something that a lot of people can do reliably.
