Upload to Pro Mini without soldering pins
The Arduino PRO MINIs usually are shipped with header connector strips to be soldered.
But sometimes you do not want to solder the strips because in your project you want a small size and do not need them.
Of course, for uploading your sketch you need to connect the Pro Mini to your programmer, e.g. the FTDI, YP-05, or whatsoever. This is how it can be done.
Be aware there are (at least) two different versions of the Pro Mini!
