@CrossRoads - Cant I use the internall 16MHZ PLL and by this, eliminating the crystal ? I can select from "BOARD" the Attiny85 @ 16 MHZ (internal PLL; 4.3v BOD).
Please dont get me wrong, if it needs the crystal I will put it there, but if I can use it without, that would be great.
Anyway I cant believe how simple is the schematic and how powerfull is this little Attiny85. Maybe for you guys, who are in the AVR world for longer time this is normal but for me its quite a surprise.
