Breadboard header for ATTiny 25/45/85
author: Vassilis Papanikolaou - vpapanikgmail.com


 


This handy breadboard header for ATTiny 25/45/85 microcontroller is a new design based on the original idea from Tinkerlog. Maybe the most useful feature is that it can provide power to the vertical breadboard strips while connecting all six port pins to the horizontal strips. Other features are :

  • 6-pin ISP connector (works great with USBtinyISP programmer)

  • easily accessible reset button

  • header for optional ceramic resonator

  • power led indicator

  • smoothing caps

Measuring approx. 4 x 2.5 cm (1Ĺ x 1 in) is a great addition to your breadboard projects saving lots of extra connections.
