I really like it! It looks like it would be very easy to use. I'd make the horizontal row that connects to V+ also square though to stop confusion. |

Looks good!
I'd take it to the next level and start thinking about connectivity with other boards of the same design.
Maybe add a "power port" or something where you've got one pad for ground and one for VCC right next to each other on the edge of the board, just so that it's easy to hook up.
Maybe a 4-pin header with a signal in / signal out plus power? I know you want to keep this board generic, so maybe that's not a good idea.
How do you hook up potentiometers? Other common off-board circuit elements that you use? LEDs?
But don't overthink it either. It looks great, and I'd get a run of them made first, and then play around with it and see what's right to change.
With prototypes like this, I've always gotta get the circuits in hand and build some stuff with 'em to see what works and what doesn't. |

nice layout. I would personally not make those (horizontal) connections for the powerpins of the IC's fixed,
which would make it a bit more universal but for CMOS it does makes sense. (although CD4049/4050 uses pins 1 and 8 )
I'd also connect both power rails from top to bottom, so the 'squares' aswell. _________________ "My perf, it's full of holes!"

Thanks.
Yeah...I'm not sure about connecting the power-pins too...
Also because it would be a nice board for a quad opamp too (even without a third power rail)...
...on the other hand I could just order 10 with fixed power connections and 10 without.
I think I will follow your suggestion of 'connecting the squares'. |
