Handy Pinout Reference Sheet

Just thought to share a quick tip today. I’ve noticed that when doing work with AVR MCU’s, I’m using ATtiny2313, ATmega88 and ATtiny45/85 for 99 % of the time. I got tired of opening the Atmel data sheets every time when swapping a new chip into a breadboard, so I constructed a real cut’n’paste reference sheet by gluing the relevant portions on a piece of rigid cardboard:

I even used a piece of paper to mark the 6-pin header pinout, it’s a real time-saver! And thanks to the cardboard back, it’s easy to keep below my LCD monitor and pull out every time I need it. Additional idea would be to leave some white space around the pinouts and laminate it with clear contact paper, so I could doodle project-specific notes with a water-based marker and clean it after I don’t need them anymore!

Oh, and as you can see, I’m using a Mac this time to do some flashing. I installed the excellent Crosspack for Mac from Obdev guys. It’s a streamlined way to install avrdude and avr-gcc on a Mac, and now I can take my electronics hobby with me when I’m traveling. :)
