The hidden problem is that "OPS" describes a slot, not a promise that everything will work. Intel's Open Pluggable Specification fixes the module's size, its 80-pin connector and its power input, so a module from one brand physically fits a panel from another. Whether touch passes through, whether the module wakes with the panel, whether the vendor will support the combination and whether the module can run the next version of Windows are separate questions, and vendors answer them differently. Add heat, power draw and a Windows lifecycle tied to the module's processor, and the "just slot in a PC" pitch has more small print than it seems. None of this makes OPS a bad idea. Being able to replace a PC without replacing an 86-inch panel is a real advantage. At SourceIT, Avocor's OPS modules start at S$1,028.75 for the Avocor i5 Gen 11 OPS with Windows 11 Pro (listed 31 Oct 2026).
What does the OPS standard actually fix?
| Item | Intel OPS specification (Rev 005, Sep 2012) | What it leaves open |
|---|---|---|
| Size | 200 x 119 x 30 mm including the mounting frame | Larger "OPS-C" modules exist, described by vendors, not by Intel; some do not fit every panel |
| Connector | 80-pin JAE TX24/TX25 blind-mate connector | How each panel routes touch, USB and audio through it |
| Power | 12 V to 19 V DC, maximum total current 8 A | Actual draw, which each module maker must publish |
| Cooling | Tested at an ambient temperature no higher than 45 °C; the panel's vents must expose the module's heat sink | Real conditions inside each panel |
| Software | Not covered | Windows edition, drivers and update policy |

Where does compatibility break down?
- Not every "slot-in PC" is OPS. ViewSonic's support pages say its older VPC modules used a proprietary 120-pin connector before it moved to the standard 80-pin OPS. MAXHUB's MT71 module for the XBoard V7 is its own "pluggable PC module", larger than an OPS module.
- Even same-brand pairings have limits. SMART's own OPS compatibility table notes that USB passthrough from a panel's front ports is not supported with one module, and that some modules do not turn on when the display wakes from standby.
- Vendors test their own combinations. i3CONNECT says it "cannot provide any recommendations" about third-party OPS modules. Avocor lists its i5 Gen 12 module for its own display series and says nothing about other brands.
- Touch is the usual casualty. Newline publishes a support article for "no touch on OPS source", with fixes that include reseating the module and swapping it for a known-good one.
We found no published document showing a pin-level conflict between two named brands, so treat cross-brand pairings as untested rather than broken. Buy the module from the panel maker's list, or get the pairing confirmed in writing.
OPS guarantees the module fits. It does not guarantee the room works.
How much heat and power does an OPS module add?
| Module | Published power | Operating temperature |
|---|---|---|
| LG OPSP-5LENA (i5-13420H) | 54 W typical, 81 W maximum | Not published |
| Promethean OPS-M4 (12th-gen i7) | 69 W operating, 0.5 W standby | 0 to 40 °C |
| SMART PCM13 (i5 or i7) | 76 to 77 W maximum, under 0.5 W standby | 0 to 40 °C |
| MAXHUB OPS72A-i7 | 80.7 W maximum, 2.9 W standby | -10 to 45 °C |
| Avocor i7 Gen 12 | Not published (12 to 19 V input) | -10 to 50 °C |
| Yealink MCore OPS G2 / G2T | Not published (12 to 19 V, 4.7 to 7.5 A) | -10 to 50 °C |
From vendor datasheets, accessed 31 Oct 2026. None of them publishes fan or noise data.
A module drawing 54 W for nine hours a day on 250 working days uses about 121.5 kWh a year. At SP Group's regulated tariff for October to December 2026, 31.16 cents per kWh including GST, that is about S$38 a year: small next to the panel, but not zero, and it is heat released inside the panel's enclosure. Modules left on overnight or in a hot cabinet run warmer. We found no data on OPS fan failure or throttling rates, so we will not quote any. See How Much Power Does Your IT Equipment Consume?
Why is the Windows lifecycle part of the problem?
The module's processor decides which Windows it can run. Windows 11 supports Intel 8th-generation Core and later, so older modules cannot officially move to Windows 11, and Windows 10 support ended on 14 October 2025. Teams Rooms adds a further rule: it needs Windows 11 IoT Enterprise or Enterprise on the annual channel, not Pro and not LTSC, so a module bought with Windows 11 Pro is not a Teams Rooms system without a different licence and image. When a Windows 10 module reaches its limit, the fix is a new module, not a new panel. That is OPS working as intended, but it should be in the budget. The full cost picture is in Android Smart Boards Are Cheaper. But What's the Real Cost After Five Years?
How do you avoid the hidden problems?
- Buy the module the panel maker lists for that model, or get the pairing confirmed.
- Test touch, front USB ports, audio and wake from standby before rolling out.
- Check the Windows edition against the room's use: Pro for a shared PC, IoT Enterprise or Enterprise for Teams Rooms.
- Check the warranty separately. Module warranties differ from panel warranties; Avocor's i5 Gen 11 listing states two years.
- Keep the vents clear and avoid closed cabinets around the panel.
- Plan the dual-system support. See One Screen, Two Operating Systems and Is the OPS Computer Included?

Frequently asked questions
Will any OPS module work in any interactive display? It will usually fit, because Intel's specification fixes the size and 80-pin connector. Touch passthrough, front USB ports and wake behaviour vary, and most vendors only test their own pairings.
How much power does an OPS PC use? Published figures range from about 54 W typical to 81 W maximum in use, and from under 0.5 W to 2.9 W in standby.
What is OPS-C? Vendors describe OPS-C as a larger module that also uses the 80-pin connector. Intel's specification does not define it, and some OPS-C modules do not fit every panel.
Can an old OPS module be upgraded to Windows 11? Only if it meets Windows 11's requirements, including TPM 2.0 and an Intel 8th-generation or newer processor. Otherwise the module needs replacing.
Does an OPS module with Windows 11 Pro run Microsoft Teams Rooms? No. Microsoft supports Teams Rooms on Windows 11 IoT Enterprise or Enterprise on the annual channel only.
