My Board Layout Diagram

[MarkHaysHarris777]

Its rather busy, isn't it?

The diagram fails to highlight power on euler 4&6; uart3&4 are not highlighted, uart0 (shown accessed on euler) is better accessed on the EXP header 7 8 &9, uart2 on PI is not highlighted, and the overall pinouts diagrams (located here on the wiki) are really too small, aren't they?

This chart is a galant effort, and if it helps you fine, but it seems too specific to be useful generally, and is just busy enough to be really confusing specifically;  which can raise more questions than it answers. On the other hand, it just may come in useful for lots of people (time will tell).

edit:  PS   Also, if you would post your pics the way I told you to, you would be able to upload your content, the pics would show as thumb-nails (which makes them easier to read by everyone), and the expanded pics would have a better resolution.

I will post specific instructions as a sticky tomorrow.
