Assembled Minimig v1.1, larger FPGA (BGA-package)

[AJCopland]

Couple of questions:
What will you do with the unused pins, bring them to an empty header/pin array for expansion?
Are there any other differences between the BGA and QFP versions of the FPGA?

PS: I'd also be interested in an assembled one, have already said I'd take at least one blank board from Xenepp so will honour that request as well.

This is why I was a bit reluctant to announce this, I wanted to get feedback from Xenepp first, to make sure he didn't end up with a large batch of blank boards.  But, I haven't heard anything from him yet, I am afraid :-(

Don't worry I'm still going to get one of those bare boards from Xenepp like I said :-D However I suspect I'll be buying many variants of the MiniMig over the coming years!

The bare board will allow me to choose components and to build one myself, however one using a larger BGA version like yours would be best pre-assembled as I can't do BGA myself.

lol well i can't comment on the technical side of it but it looks like all the main blocks I can identify are there. You'll have 10 user_io pins left. All 16 of the CPU address and data lines, likewise for the ram.

After that it all starts to look like a complicated game of scrabble :-D

Whilst 020 or 030 would be nice for a later revision I think this particular v1.1 revision is just to give us more pins to do things with from an expansion point of view. Though it is ThomasML whos doing the work on this version so he'd have a better idea.

Also adding an 020 or 030 has been discussed and seems like a major redesign of the board for a seemingly large number of reasons. Everything from voltages through clock speeds via board trace layouts etc and a bunch more stuff I didn't understand ;-)
