Re: TQFP Programming Adapter

2007-11-29 by Bob Gardner

As the OP here, I appreciate all of the responses.  My original 
intent was just to save a little space on what I hope to be a fairly 
small board and I have to admit I hadn't really thought through some 
of the possibilities that evryone has brought up.  I don't have any 
problems with providing test points for a 6 pin ISP adapter of some 
type.

Along those lines I have done some internet searching but didn't come 
up with anything in particular.  Can anyone provide more detail or 
even some links for some type of narrow pitch adapter I could make or 
buy to use with some test points I would put on my board?

Thanks again,

Bob
