  • Pushbutton-style 16-key keypad
  • 8-pin connector (0.025" square pins)
  • easy pin connections for breadboard, ribbon cable, etc.
  • corner mounting holes
  • compatible with #2 mounting hardware (not included)
  • currently shipping black keypad (not white)

 

This keypad has the connector on the rear, along the bottom edge, as shown in the photos. It consists of a single strip of eight square pins, on 0.1-inch centers. Here are some ideas for making connections:
- wire-wrapping
- plug into a solderless breadboard
- plug into one half of a 16-pin DIP socket
- plug one row of a 16-pin ribbon cable over the pins and the other end to pins in your project board

A rough schematic of the keypad can be found here, showing the row and column pinouts: http://support.technologicalarts.com/docs/Components/MK4X4.pdf
