I made this breakout board for the ATtiny45/85 because I got tired of setting up my projects on a breadboard and tying up a breadboard. This breakout board allows me to prototype faster with the screw terminals and the AVR pin headers, seat the microcontroller and it stays there until the project is done and a pcb is made for the application. Unlike breadboard prototyping programing is done right on the board through the AVR headers. There is no crystal on this board so the frequency relies on the internal crystal 1MHz or 8MHz are the frequencies. The cover picture is an old rev of this board I added mounting holes and the power connector and the reset button and resistor also got moved for better tracer routing.
