Being smarter with minimal AVR development board

Sometimes simplest ideas work best. If you like prototyping a lot, then you know, that building complete circuits on a breadboard can be pain. If your projects include microcontroller like AVR this part is always the same – micro and programming header. It may be OK if part is through hole, but if it’s in SOIC package. Baoshi found a simple solution to this routine.

ATTiny2313-development-board

He used common 28 pin SOIC/SSOP to DIP adapter and soldered microcontroller here. Then on remaining pads he soldered ISP header on top. Of course he had to bend legs to make it fit on surface. Since there is another SMT footprint on bottom, here he could electrically connect programming header to corresponding programming pins. This way without significant investment, he made robust module, that can be plugged to breadboard and used right away. As someone suggested, there are still place for decoupling cap and probably other support circuits. Great idea and time saver.
