>> As i mentioned earlier in the thread this is the old style boards (non
RoHS), Just wondering at this point if there is a component value that might
be incorrect on all 8 stage boards.

6.7v when pressing the button so i figured this might have something to do
with resistor values.

silkscreen rev A and the picture of the rev b boards on the CGS site.
>The row of resistors closest to the LED and diode on my board are (in order
of closest to farthest (47k,47k,470k,820r,680r) and the CGS site with the
revB boards (47k,150k,470k,820r,680r)

>Now to further complicate things i was following the values listed on the
website, BUT i got the 47k and 150k REVERSED which probably explains the
voltage drop.
>My question here is, Which should i follow for these REV A (non RoHS)
boards. 47k, 47k, or 47k, 150k?
