Burnin.

Without revealing too much about your boards can we get any updates on design specifics. I know comparison with Bkkcoins version of a DIY Avalon will help many see that diversity is in the marketplace and will help everyone a great deal to get into more CHIP group buys. We do need as much information as possible so that we can settle people into the alternatives. BFL has a very tenuous hold on the market right now and the more project leaders can reveal the better to loosen BFL's grip and allow for more freedom in the market place.

# 10/20 Avalon chip module - 2.82/5.56 Ghash/s nominal speed
# 4 Layer thermally enhanced PCB
# PIC32 native USB-Controller
# CAN-Bus inter-module communication (Only one USB connection for up to 32 Modules)
# Power Connectors: 6Pin VGA, barrel jack for wallwart, power-stacking-connector.
# Power requirement: ~20/40 Watts @ 12V
# Onboard 25A/50A switcher for core voltage
# Easy stacking option
# Host protocol: Avalon emulation
# Temperature controlled Fan

Seeing that there is no FPGA means a lot so you are in agreement that most of these 10 -16 chip board designs and larger configurations do not need it?

Also in terms of stacking we are looking at a 600 W PSU that could supply power to how many boards?

So in terms of heat sink what will you be using Aluminium extruded like on the Avalon rigs?

The heat sinks will be connected to vias to dissipate heat or do you have something else in mind?

My apologies if this has been answered before in the thread. I will continue reading through and revise if necessary.

When you get time Burnin unless this has already been asked an answered.
