What about this? Your free reference guide to electronics.

The Hardware Book is a compilation of pinouts I've found from different sources. I've tried to have the same style for all pages. This makes it easier to find information for you. I am not trying to sell anything.

It has been developed on my sparetime and is made available to you for free. This also means that I can't guarantee that the presented information is correct. Use it on you own risk. I can't take the whole credit for HwB. I have since the first release received a great lot of mails with suggestions, questions and information. With the help of many contributors HwB has grown. Keep sending me mails...

This is me, Joakim Ögren:
