Open Pluggable Specification

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 benefits of using OPS in digital signage are to reduce setup time and improve integration, while also reducing downtime and maintenance cost by making it extremely easy to replace the computing module in case of a failure.[2][3]

Technical specification

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