Quoted from Ilikewires:Thanks for the positive comments..
The boxed connectors were nice for prototype testing alone, so I am sure folks will like that.
The DC/DC converter is designed for 2A, and the board draws much less than that. I would estimate about 10W or so, so it is a light draw on the 12V.
You are right about U20, but there were limited options there. But I do give you a 90 day warranty, so if you have bad switch wiring and pop the board, at least it is my issue to replace it.
My biggest fear is the customer struggling to remove and replug their ASIC chip from old to new board.
Do you all think that it is worth getting a license to provide the EPROM with the board?
Right you are on the parts availability.. it is mayhem out there. I shifted an automotive design for a client to a different part, and a week later we could not get that part either. They found 30 pieces at a broker, and when they arrived, they put them in the safe with the gold that they use in their manufacturing.
The rest of the first 100 production run of the MPU89 will ship to me at the end of this week.
Sound boards.. sigh. I do have some early designs on some nice sound board stuff.. but if there is anything that I have learned on Pinside, if you hint at a project, folks want a price and delivery. But yes, there is some early work on some sound board work.
I think this is a step in the right direction. SMD components are a challenge to repair, but when older part styles become obsolete, we have to adapt. You have implemented a good solution with the DC/DC converter. I did not like working on SMD boards at first, still don't but just have to. My 2 cents is all I am saying.
