[sdiy] fmmt489

Aha, point taken.

Time for our friend to dig through data sheets then. ;)

And, another interesting thing which you already have pointed out; it
*does* look like you did an all thru-hole board, and it might be more
trouble than its worth to search out an obscure part when mounting
will cause some added difficulty.

Unless you have already completed an SMT board? If you have, count me
in. ;)

Only reason I strayed from the project is that I just *love* SMT
completely, and currently, it looks rather large.
