IDC Breakout Helper - 2x8 (16 pin)Adafruit
This 2x8 (16 pin - 0.1" spaced) IDC Breadboard Helper is great in conjunction with any 16-pin IDC cables. It comes in two parts, a 'pin-through' socket and a male header. The socket straddles the center of a breadboard or Perma-Proto and then header plugs into the top of the socket. Since IDC cables are so standard, but a royal pain to use with breadboards, this is a good and cheap hack for prototyping.
Works best when soldered in place. We have used these to prototype on a solderless breadboard but some customers report their breadboards don't play nice with the shorter pins so your mileage may vary
Each order comes with one socket and one header. Breadboard, Perma Proto and IDC cable not included!
