Loving the use of strip-board - you must be a glutton for punishment!

It takes 2 weeks to wait a for a board ... just to find out you've messed something

I've made a small board for just the chip with caps - the rest is easy to be put even on a strip-bard and this way i could also swap the chips at will and test the differences between them.
Now I am (almost) sure the prototype will work as expected
Does your small board even have solder-resist? I'm very impressed if you managed to put the QFN's down without it!
