The following update was posted to the Butterfly Labs Forum regarding their updated platform.
The new boards for the Little Single, Single and Mini-rig pictured below. As you can see, the board redesign incorporates a total of 16 possible chips, as well as some power distribution changes. One of the more prominent changes is the fact that we have moved from barrel jack power to PCIe style Mini-fit Jr 6 pin connectors. Each board has two 6 pin connectors to provide power, and each board is intended to provide up to 60 GH/s hashing power.
We discovered some issues that we needed to resolve with the boards and had to change a few minor things. We tested them out on a hand modified board and they worked, so we've issued the redesign to the PCB house. The new boards are being finished today, the 6th of May, and should be ready this evening. We have more chips from the packager on the way to the assembly facility, and they should arrive on Thursday, the 9th of May. In the meantime, we will be testing and making sure the new board is functioning like we intend for when the chips arrive to the assembly facility. We don't have a count on the number of chips that will be arriving on Thursday as of yet.
The current board will support the hash rates ordered for Little Single and Single in one box, so single units will be shipped out for both the Little Single and the Single. The Mini-rig will most likely ship as two units (where as it was just one before) and possibly some Singles to bring it up to the full hash rate ordered. 5 GH/s miner production will continue concurrently with the rest of our product line. We are incorporating some changes into the new 5 GH/s miner to bring the heat and power usage down, and that will be incorporated as we go forward. Power usage on the new boards hasn't been tested yet as we are waiting for the revised board, so I don't have power figures for it yet.
