Open Pluggable Specification (OPS) is a computing module plug-in format available for adding computing capability to flat panel displays.

The format was first announced by NEC, Intel, and Microsoft in 2010.[1]

Computing modules in the OPS format are available on Intel- and ARM-based CPUs, running operating systems including Microsoft Windows and Google Android.

The main benefit of using OPS[2] in digital signage is to reduce downtime and maintenance cost by making it extremely easy to replace the computing module in case of a failure.

Technical specification

  • A computing module fully enclosed in a 180mm x 119mm x 30mm box
  • JAE TX25 plug connector and TX24 receptacle
  • 80-pin contacts
  • Supported interfaces:
