Is this easy enough to understand?
Or option B, based on @xabean's suggestion:
@arturo182 @xabean I like this version for clarity better, i think it looks better too!
@arturo182 @xabean I like this version better. I think it better communicates that GND and 3.3V span two pins.
@arturo182 @xabean I got it off the first but that's even more unambiguous.
@arturo182
@xabean
That's better, although I would be tempted to split the Gnd and 3v3 so it says
Gnd Gnd
3v3 3v3
@arturo182 B is better, but the lines still look overcomplicated. How about this?
@arturo182 @xabean Option B is even better. 😄
@arturo182 sure, pin numbers from row to row, the two bottom rows have the same power signals.
@arturo182 I read this as saying: The top eight pins are 36-43. 36-39 going down in the left column, 40-43 in the right column, below is a row (left and right) of GND below that a row of 3.3V.
@arturo182 I think it'd be more readable if the bar separating the number pairs looked less like a 1 or I -- maybe if it was taller or just split the inverted region entirely.

@arturo182 yes, this is good.

Just make sure the silkscreen process your fab is using is actually capable of properly printing this. Some fabs have quite low resolution for silkscreen.

@arturo182 yeah, option B for sure
