Well part of the advantage is I don't have to write a driver for it, which is good since I'm already doing everything else (and probably also code work, since the guy who's supposed to be helping hasn't gotten back to me in 3 weeks) for a couple other projects right now - on top of manufacturing and hosting. If someone wants to port over S5 code to work with a USB/UART controller, this guy would hook right up to it - except you wouldn't have a temp sensor since that ties in through I2C on the 18-pin header. I had a board design about Christmas with all that stuff integrated, and I handed it to Novak for firmware but he never got around to it and then he left for a freakin' sweet rocket scientist job so it's not gonna get done in any time frame where the BM1384 is even really viable as a hobby miner, not when I have A3218 and BitFury projects already underway.
