Beguiled by a fancy new chip that is only available in a SOIC or (T)SSOP pinout? This breakout PCB set will make your life much much easier and get you prototyping faster than ever. One side has a 12-TSSOP pin out with traces going to two rows of 0.1" spaced holes, the other has 12-SOIC. Solder your chip to either side and you're ready to rock on any solderless breadboard.
Each item comes with six PCBs, each PCB is identical and can support either a SOIC (narrow, medium or wide variety) or TSSOP. Standard thickness PCBs, with 0.6" spacing between the two rows. You can, of course, use a smaller chip but the pin numbering won't be right - so use care.
