the .BRD file currently downloadable from arduino.cc has apparently been fixed, and has the 160 mill separation
OK, I get it.
And now, for my last words on this thread (I promise):
I have already indicated that the 150 mil separation on the original Mega board (the 1280) presents no problem for me. If other people say it's a problem for them, I won't argue.
A problem that I do
have is with documentation. The downloadable design file for the Mega2560 has the same name as the file that I downloaded on October 1 (when the world was young and I was still an Arduino Idealist). When I unzip the current download file, the .brd and .sch files have the same names as the older one, but the current .brd file has a date of October 10, whereas the original one had a date of September 26. (The .sch files have the same date, September 26, but the times are slightly different.)
I see no difference between the two schematic files (but I didn't look very hard).
The only difference that I observe between the two board files is that the "PWMH" header was nudged to the left 0.010 inches (10 mils) so that the separation is, indeed, 0.16 inches (160 mils). I am quite sure that I wouldn't have noticed that
if I hadn't been looking for the specific coordinates.
More important (to me, at least) is the following:
I see no indication of revision number on the schematics or the boards themselves. So here are a few questions that I have. (Since I won't be replying, you can consider them rhetorical, although I wouldn't mind seeing opinions of anyone who chooses to express them.)
- Shouldn't there be something on the silkscreen (or copper) on the board to indicate which revision people are actually holding in their hot little hands?
- Shouldn't these revisions be documented somewhere?
- Shouldn't download file names be changed when the contents change?
Of course, I may be missing something. It wouldn't be the first time (not even the first time today).
