This product is an SOIC 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 are .65mm pitch adapter boards for 8 leads, 20 leads, and 28 leads. The 20 and 28 pin boards also include room for 0805 SMT components such as a bypass capacitor and pads for easy access to a ground. A standard row of 40 headers has been included as a bonus for your convenience.
