OAK-D LR: standalone after eMMC removal, NOR flash limits, no Hub

rak-satyaki

We are specifying OAK-D LR for a production industrial deployment on an **isolated network

with no internet access at all** — no Hub, no outbound connectivity, permanently. 4 units

initially, 8–16 in production.

I have read the Standalone modeand Bootloader docs, plus/d/1655-standalone-mode and/d/5760-oak-som-pro-missing-emmc,and I could not resolve the following.
1. Standalone after the eMMC change. The OAK-D LR page states that units manufacturedafter May 2026 will not include eMMC. The standalone docs state standalone requires on-boardflash. Does that mean current-production OAK-D LR cannot run standalone?
2. NOR flash versus eMMC. Some OAK boards carry 256 Mbit (32 MB) NOR flash separately fromeMMC. Is standalone mode supported from NOR flash alone, and what is the practical sizelimit for a `.dap`? A YOLOv8n blob is roughly 10–15 MB, so I want to know whether one detectorplus a small second model realistically fits in 32 MB, or whether eMMC is required in practice.
3. Can eMMC still be had? If it is needed, can it be specified as a build option, and isthere a minimum quantity? The OAK-SoM-Pro thread suggests population varied within a singleorder, so I would like to know whether this is selectable or incidental.
4. Connectivity. The shop listing shows RJ45 with PoE alongside USB-C; theOAK-D LR docs page lists USB only.Which is correct for current production? If RJ45 is available, **can the device stream to ahost elsewhere on the network** rather than one physically attached? This matters because thehost would otherwise have to be mounted on moving equipment.
5. Fully offline operation. With models deployed manually, can the device run indefinitely with no Hub account, no activation call and no licence check — nothingphoning home at boot or during operation? Does any function degrade without Hub?
6. Local conversion. Can PyTorch/ONNX → OpenVINO Model Optimizer → Compile Tool → `.blob`be run entirely on our own machines, with no upload to a hosted converter? I take it thehosted BlobConverter is a convenience rather than the only route, but I would like thatconfirmed.
Thanks — happy to be pointed at docs I have missed.

Hey rak-satyaki - OAK-D LR is an RVC2 device. Units manufactured after May 2026 do not include eMMC, and RVC2 standalone mode is now deprecated.

A standalone application can use NOR flash if the complete DAP fits. The model size alone does not show if it will fit. The DAP also contains the firmware, pipeline, assets, alignment, and package overhead. We do not publish one practical DAP-size limit that applies to all OAK-D LR board revisions.

For a new standalone product, we recommend that you also consider an OAK4 device. OAK4 uses RVC4, where standalone operation is actively supported. This avoids making a new product depend on the deprecated RVC2 standalone mode. However, OAK4 and OAK-D LR have different camera and depth configurations, so we must confirm that an OAK4 model meets your range and field-of-view requirements.

The OAK-D LR supports 1 Gb Ethernet, so a host can connect to it over the local network without a direct USB connection.

Luxonis Hub does not apply to RVC2 devices such as OAK-D LR. You can convert an RVC2 model locally.

For 8–16 units, please contact support@luxonis.com before ordering. Include your required depth range, field of view, models, and expected application size. We can then help select an OAK4 alternative or confirm the storage configuration of the planned OAK-D LR batch.
