DIL / SOIC / TSSOP Experimenting Boards

Whenever you want to put a circuit together quickly, it will take too long to design a PCB for it first. In that case, the experimenting PCBs shown here are eminently suitable.
Three variations are available: 20-pin DIL package, 20-pin SOIC package and a 20-pin TSSOP package. If you use an IC with fewer pins, then you simply don’t use some of the solder pads.
