This product is an QFP/QFN to DIP adapter with a twist. These have our patented "ez" technology which means that soldering the surface mount component is simple, and as with all of our "ez" boards, we are the only company with a patented solution for easily soldering surface mount parts. Included in the package is 0.5mm pitch adapter board for 40 Lead QFP or QFN and a row of headers to use the boards with a breadboard. This board also includes room for 0805 SMT discrete components such as a bypass capacitor and pads for easy access to a ground. Additionally a plated hole in the center of the device area, allows for the addition of solder to utilize ground pads on the bottom of the IC. A standard row of 40 headers has been included as a bonus for your convenience.
