An SMT breakout (stands for surface mount technology) helps in providing a prototyping solution.
Beguiled by a fancy new chip that is only available in a QFP or QFN pinout? This breakout PCB set will make your life much much easier and get you prototyping faster than ever. One side has a 48-QFP pin out with traces going to two rows of 0.1″ spaced holes, the other has 48-QFN (7mm body). Solder your chip to either side and you’re ready to rock on any solderless breadboard. There’s even a THM pad on the opposite side of the QFN body pad so you can fill it with solder for a heat sink and/or connect a wire to it (say when the pad must be grounded).
Each item comes with three PCBs, each PCB is identical and can support either a 7mm square QFP or 7mm square QFN chip. Standard thickness PCBs, with 0.7″ spacing between the two rows. The PCBs may come on a supporting strip of PCB, simply snap them off to use!
