Surface mount breakout boards

We got a hold of some DS3232 RTC chips in a 20-pin SOIC package. We’d like to have one that is breadboard compatible for easy prototyping but when we searched for SOIC20W breakout board artwork we found none. We used Eagle to design our own and you can see the finished product above which we made using the toner transfer method and cupric chloride.

You’ll find the artwork after the break in case you need to make your own breakout board some day. If you know of surface mount breakout board artwork that is freely available please leave the link in the comments for future use, or send it to us on our tips line and we’ll add it to the post.

Incidentally, the DS3232 is the same as the DS3231 used in the ChronoDot but with the addition of some SRAM. We’ll let you know if we come up with an interesting project for it.

Update: We added 28 SSOP to DIP artwork submitted by [Paul Dekker]
