Some time ago there was a post on the forums here of, what I think, is was the smallest Arduino.
This guy soldered the few components (crystal, capacitor, etc…) that were needed to run Arduino directly to the processor or maybe he used a pin header. Not sure…
I have been looking for that thread last night but not been able to find it. Anyone remembers the thread I talk about and can link me to it?
Thank you in advance!
