The circuit board header of the ATTINY85 microcontroller is a new design. The most useful feature is that it can provide a vertical breadboard with power connections when all 6 port pins are horizontally connected. Other features are as follows:

6-pin ISP connector (Engineering USBTInyISP programmer)

Convenient reset button

Ceramic resonator with optional header

Power LED indicator

Smooth cap

& TImes; 2.5 cm (1 ½ X 1): good addition to saving a lot of extra connections for breadboard projects.
