Hi, Why the pinout of the board is so protoboard unfriendly?

I had to tear apart my protoboard to make it work ok...

take a look at

Yes - it is pretty daft, isn't it?!

If you look carefully at the left of this photo, you can see that I adopted exactly the solution as you:

Here's a close-up:

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

Not what I would call ''protoboard friendly'' for sure... But it wouldn't really be a big deal to lop the P3 pins off since they are not going to be mating anyway.

Just a thought :)

Still a pain if you actually wanted to use those pins...

Yes, the easiest ''fix'' for ST (without re-spinning the board) would be to simply not fit those pins.
