This 2x16 (32 pin - 0.1 spaced) IDC Breadboard Helper is great in conjunction with any 32-pin IDC cables.
It comes in two parts, a 'pin-through' socket and a male header. The socket straddles the centre of a Perma-Proto and then the header plugs into the top of the socket.
Works best when soldered in place (they don't always stay put in a breadboard).
Each order comes with one socket and one header. Perma Proto and IDC cable not included!
