I used a small saw for structure building small miter box saw or track cutting saw. Saw a little on both sides and the module comes apart cleanly. I did start at the rounded top end until the saw went flat.
Great upgrade, especially jumping from 1.2. Also I have two new "black mods" after I do John's modification. now I have too many black modules...last month I had a hard time finding them and paid $17.95 for one. Thanks Gunrunner.
Glad it worked out for you. Did you see the "upgraded" modification involving moving the zero ohm resistor? Given that it's pretty easy if you use wire and not try to position that little resistor, I recommend that method if possible. I would have initially done that, but I didn't tumble to the fact that the resistor was a configuration jumper.
While I really don't believe that there's any realistic possibility of having enough capacitance with that pin cut off to be an issue, Jon had a point that anything's possible. If you ground the pin by moving the jumper, there is zero chance that it'll ever be a problem, so if possible, that's what I'd do.
