These are PCBs that allow you to incorporate ICs in a SOIC (Small Outline IC) package into a miniTesla project. You will be able to solder such ICs onto these PCBs. Some ICs are no longer being manufactured in DIP (Dual In-line Package). You will get two boards for 8-pin SOIC, two boards for 14-pin SOIC, and two boards for 16-pin SOIC.
They all have a place where one can solder an SMD decoupling capacitor. The capacitor pads are connected with pins 4/8 for SOIC-8, pins 7/14 for SOIC-14, and pins 8/16 for SOIC-16. The 8- and 14-pin boards have pads for a second capacitor that is connected between the first and last pin, pins 1/8 for SOIC-8, and pins 1/14 for SOIC-14.
