UNO SMD: using A6 and A7, DIY

Some Arduino Mini or Nanos come with pins for the analog inputs A6 and A7. But the UNO does not. If you are experienced in soldering small items and have good glasses you might give it a try:

But make sure the wire is fixed to some solid place. Don't pull it!

Just in case you do not know: A6 and A7 are analog inputs only. You cannot use them for digitalRead or digitalWrite.

Even the internal pullup-resistors attached to all the other pins don't exist on A6 and A7.
