Ahhh.... it's been a while since I've seen my creations
And by the way if you have any questions on them or if I could be of any help with reusing parts of that design - let me know.

I already know that the voltage regulator will not be a good fit - it's lower limit is 0.8V (although the dual-chip version used a 6A one which might still be usable). Ripples were quite significant too - 30mV (but that might also be within the tolerable limits). It was a very cheap option though (and which is why I used it)

And software is the other major issue - currently the design is stuck with this USB-Serial chip as this is what cgminer supports and that's the only documentation on the BM1384 (yeah! seriously!). The specific USB-serial chip is not really bad but an alternative one could easily save another buck or so from the final price. I guess for the moment that's a reasonable compromise - spend a bit more on components and a lot less on software development.

Oh - and almost forgot - note that black heatsink! We paid a bit extra for them but they were well worth the money and in terms of performance they exceeded the competition by a large margin! Really good ones! The downside is that they were 40x40mm so the board was redesigned around them and that's why it is a bit bigger.


And kudos to novak and sideshack! Great job!
