Yes, I etched the new board and it turned out great. I'm waiting for a
parts order to get here and I'll build it, should be here tuesday. I am
going to use the first board too, to build one for my son, he is a ham
also. I been getting more and more into the smd stuff, but 1206 is my
preference. I have a microscope and all the tools needed for the
smaller stuff, but not the coordination. Hi, Hi. Jerry K5LRU

Hi team,
@Jerry, did you etch the new board, is it ok now? I am sorry that you
have to waste time etching the first one, with small pads.
Regarding LM1117-3.3v, it is a TO-252 package there. I put this one
because I don't think this regulator comes in to-92 package, at least I
couldn't find on ebay or on my local suppliers (www.tme.eu). Other
options were TO220 or sot 232, both are either to big or to small.
Anyway, If the board was for me only I would have done it full SMD,
except some parts of course. From 2 years ago I work only with SMD,
1206, and I found it that is easier and fast to solder than tht's, even
without a magnifier. Now, I want to try implementing 0805 or small :)
Its even cheaper with smd. I bought from ebay 1206 assorments kits, with
resistors and caps, with 12-15$, sets with over 70 values @ 20pcs each
that will last me for years. I have only bought extra 100n @ 200pcs
caps, beacuse those ones are used the most.
Maybe in future I will make a SMD Minima also.

Mac, I've attached a picture of the TO-252 for you. If you don't like
using that package, the LM1117 also comes in the TO-220 package, for
which you would have to drill three holes. The whole digital board can
be built using through hole parts just by drilling 7 extra holes. Why
would you ask someone to redesign a board when all you have to do is
drill 7 more holes. The si570 is what it is and in the only package
available. Jerry K5LRU

Correction - The package the LM1117 needs to be in an SOT-223 package.
