This is a bundle of two 204-0017-01 adapter PCBs and the 920-0031-01 solderless breadboard. Each PCB is a QFP/QFN-to-DIP adapter with a twist. These have the patented Schmartboard|ez technology to make soldering surface-mount devices easy. Your SMT part will sit in grooves that hold it in place and already have solder in them. So all you need to do is put a chip in the grooves, apply flux, and use a small enough soldering tip. Each adapter supports a 32-pin QFP or QFN device with 0.5mm pitch (5×5mm body). The board also includes room for 0805 SMT discrete components (e.g. a bypass capacitor), and pads for easy access to ground. Also, a large plated hole in the center of the device area allows for the addition of solder to utilize ground pads on the bottom of a device. Two strips of 40 male pin headers are included. These strips can be snapped apart so that you can create the individual 16-pin segments needed to complete the 32-pin DIP package. The leftover headers will be just enough for the 0805 component pins. There are unconnected through-holes on the board too. If you want to use those for mounting, you should pick up another strip of pin headers using the option box at the bottom of this page.  The Bred Blox solderless breadboard has 830 tie points (126 five-point terminals plus four horizontal bus lines of 50 test points each for easy connections to common lines). The board has interlocking features so that you can connect multiple Bred Blox together to make a larger prototyping area.
