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

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?

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.  Smiley

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.

 Shocked 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.
