Each mining board utilises 8 CoinCraft A1 chips and each motherboard can control 8* mining boards (*mine is a prototype with only two connectors soldered on). An external controller is required - which for now must be a RaspBerry Pi. Per mining board:

https://i.imgur.com/AXm1t8k.png 1) Powering (top) (#post_contents) The Sampo packages do not come with a power supply, and both the motherboard and hashing boards must be powered. You will need a typical computer PSU with:
Estimated power consumption per mining board is as follows:
I would recommend the following PSUs:
https://farm6.staticflickr.com/5463/13855097095_3a18a1c20a.jpg (https://farm6.staticflickr.com/5463/13855097095_d4f28e922a_o.jpg) https://farm3.staticflickr.com/2902/14029746209_965d6f8c7b.jpg (https://farm3.staticflickr.com/2902/14029746209_0f689cc31f_o.jpg) https://i.imgur.com/AXm1t8k.png 2) Cooling (top) (#post_contents) Mining boards come with two heatsinks each. The top uses a 2U Dynatron heatsink with an RPM limited 80x80mm fan, copper base and integrated heatpipes. The bottom heatsink is a 1U copper heatsink with a 70x70x15mm FirstD FD7015H12D centrifugal fan. Noise levels aren't terrible but they're definitely higher than an AntMiner S1. Both can be replaced with larger (and quieter) LGA2011 or LGA1366 socket heatsinks as long as the heatspreader area is huge (larger than the normal 40-45mm x 40-45mm due to the chip layout. You will need to mount them with the provided super long screw, spring and nut combination as you can't use a backplate. Remember you will significantly increase the size of these boards by replacing them, risk bending the boards and not having sufficient contact area. Even the biggest heatsinks (http://goo.gl/0eqfg8) for this socket may not be appropriate. A 120mm fan is required to blow over the voltage regulators which can reach up to 100C if left to passive cooling. Every little bit helps to increase lifetime.

A 120mm fan blowing around would be recommended just to keep airflow going. Shipped weight of a motherboard and single mining board is 2kg, dimensions of the shipping box are 195 x 295 x 330mm. Dimensions of the motherboard are 185 x 85 x 4*mm (*+60mm for cabling) and the mining card are 285 x 155* x 100mm (*+40mm for cabling). https://i.imgur.com/AXm1t8k.png 4a) Configuration (top) (#post_contents) An external controller is required and currently only Raspberry Pis (http://goo.gl/cKzGXq) are supported. Noncetech do have plans to create a GUI miner via web interface, however for now configuration is rather complicated. Cgminer is not currently supported, but will be shortly. You will need the following:
Code: sudo apt-get update
nominal.conf Code: { turbo.conf Code: {
Code: sudo nohup /home/pi/cgminer/cgminer -c /home/pi/cgminer/nominal.conf
Code: sudo nohup /home/pi/cgminer/cgminer -c /home/pi/cgminer/nominal.conf
Code: sudo nano /etc/xdg/lxsession/LXDE/autostart
Code: @/usr/bin/lxterminal --geometry=90x35 -e sudo ./cgminer/cgminer -c /home/pi/cgminer/nominal.conf
Code: sudo apt-get install x11vnc
Code: [Desktop Entry]
https://i.imgur.com/AXm1t8k.png 4b) Overclocking (optional) (top) (#post_contents)
Code: sudo nano /etc/xdg/lxsession/LXDE/autostart
Code: @/usr/bin/lxterminal --geometry=90x35 -e sudo ./cgminer/cgminer -c /home/pi/cgminer/turbo.conf

Our graphical user interface will be ready in just a few days to make the setup and control easier. At the earliest it could be ready by tomorrow morning. Title: Re: [Guide] Dogie's Comprehensive Noncetech Sampo Setup [HD] Post by: Noncetech on April 23, 2014, 09:10:47 PM The GUI is ready and just needs to be tweaked. Here is a screenshot of it:

Title: Re: [Guide] Dogie's Comprehensive Noncetech Sampo Setup [HD] Post by: dogie on August 22, 2014, 05:52:46 PM How many people actually have one of these? ??? Very, very, very few. They designed a custom PCB from scratch but failed to sell any significant number and so stopped producing. They also developed a custom web UI for these but unfortunately for us it was never released. Title: Re: [Guide] Dogie's Comprehensive Noncetech Sampo Setup [HD] Post by: cannachris on December 11, 2014, 08:30:42 AM I have one for sale fully set up with raspberry pi. Located in the Netherlands. Runs extremely stable@ 250 Gh with 0% rejects on any site, even nicehash. Drop me a line if you're interested.
