I have some 32 pin zif sockets but the pins are too short for breadboard use. In any case I need the zif sockets to stand high of the breadboard because of all the surrounding wiring. This circuit board allows me to mount the zifs on a board with 21mm extra long pin headers giving me a about 15mm clearance when the pins are in the breadboard.
