NVIDIA Jetson Xavier & TX2 End-of-Life: Last-Time-Buy and Migration to Orin

Jetson Xavier end of life came early: NVIDIA brought forward the end of life of its LPDDR4-based modules, the Xavier NX, AGX Xavier and TX2 family, because of the global shortage of LPDDR4 memory. Last-time-buy orders closed on 1 July 2026, and NVIDIA ships the final modules against placed orders until 15 July 2027.

If you run any of these modules in a fielded product, the choice now is how to cover the remaining demand from stock already ordered or still in the channel, and how quickly to move to NVIDIA Jetson Orin. Most programmes do both, and the two decisions are best made together.

This guide sets out which modules are affected, the dates, the Orin module that replaces each one, what changes in the carrier board and software, and how to plan the stock that bridges the gap.

NVIDIA’s end-of-life notice covers the Jetson modules that still use LPDDR4 or LPDDR4x memory. All were released in 2021 or earlier.

NVIDIA lists each part number on its Jetson product lifecycle page, and dates can differ by part number, so confirm the exact position of every module you buy against that page and against your supplier’s confirmation.

The dates that matter

The last-time-buy has passed, so new supply now comes only from orders placed before 1 July 2026 and from stock already in the distribution channel. Our answer on how long NVIDIA Jetson is supported sets out the lifecycle of every generation, and existing Jetson Xavier computers remain available only while stock lasts.

Jetson modules normally carry long, published production lifecycles, which is one reason they are trusted in industrial designs. The 2026 memory shortage cut that short for the older generation. As the industry moved to LPDDR5 and LPDDR5X, LPDDR4 supply tightened and prices rose, and NVIDIA brought forward end of life for the modules that still depended on it.

The newer Orin family uses LPDDR5 and Thor uses LPDDR5X, so neither is affected. In effect this is a generational transition that was always coming, pulled forward by the memory market. It also shows why lifecycle planning matters: the end of a module can be set by a component inside it, not only by the module’s own roadmap.

The Orin family replaces every affected module, and NVIDIA lined the modules up so that each Xavier design has a natural Orin successor in a matching form factor. Our comparison of Jetson Orin vs Xavier covers the generational step in depth; this table is the migration map.

Orin figures are sparse INT8 and Xavier figures dense INT8, so the real-world gain on a given model is smaller than the headline ratio, though still large. The TX2 figure is FP16 TFLOPS, as NVIDIA quoted it. Our answer on what replaced the Jetson Xavier gives the short version, and the Jetson modules comparison helps where the workload has grown and a larger module, or Jetson Thor, may be the better target.

Largely, but not as a module swap. Orin NX shares the 260-pin SO-DIMM form factor of Xavier NX, and AGX Orin shares the 699-pin connector family of AGX Xavier, so many carriers support both generations after a revision. Several differences still need checking before a Xavier system becomes an Orin system.

Is AGX Orin a drop-in replacement for AGX Xavier? The connector family and size match, but power, I/O and software do not, so treat it as a new hardware revision. Our guide to choosing a Jetson carrier board covers what to review, and our explainer on the SO-DIMM covers the connector the smaller modules use.

The software step is often bigger than the hardware one. Xavier tops out at JetPack 5.1 and TX2 at JetPack 4.6, while Orin runs JetPack 6 and moves on to JetPack 7.2. Our guide to NVIDIA JetPack explains how each release fixes the operating system and libraries.

Three pieces of work follow. The carrier’s board support package and device tree have to be ported to the Orin release. Every TensorRT engine must be rebuilt, because engines are built for one GPU and one TensorRT version. And the application and its dependencies have to be validated on the newer CUDA, cuDNN and Ubuntu. Application code usually carries across with little change, because the CUDA programming model is the same.

Two clocks were running: the last-time-buy and the migration. The first has stopped, so the question for a fielded Xavier or TX2 product is how much stock you hold or have on order, and whether it covers production, repairs and spares until the Orin version is approved.

Size the bridge from an honest forecast rather than the original build plan. Count remaining production, warranty and repair returns, and field spares for the service life you have promised, then add a margin for yield losses in rework. If the total exceeds what was ordered by 1 July 2026, distributor stock is the remaining source; buy only through authorised channels, because grey-market modules carry counterfeit and storage risk.

Store the modules correctly too. Keep them sealed in moisture-barrier bags with desiccant, in a dry, temperature-controlled store, and track the moisture sensitivity level so boards are baked before reflow where needed. Plan a requalification check on stored stock before it goes into production years from now.

This is not a theoretical transition for us. We have shipped AGX Xavier systems into counter-drone optical tracking, IP67 waterproof aquaculture and rugged construction vehicles. The same applications move to Orin, and our Jetson Orin specs reference shows the modules the migration targets sit in.

Several systems in our range show the path within one product series. Neousys offers the NRU-51V with a Jetson Xavier NX and JetPack 4.6.1 for fleets that must keep their validated stack, and the NRU-51V+ with an Orin NX or Orin Nano for the move, keeping the four synchronised GMSL2 camera inputs, 10GBASE-T and the GPS PPS input. The table shows Orin successors for the most common Xavier roles.

As your system integrator we manage both sides: sizing the bridging stock against your forecast, and designing the Orin system, module, carrier board, thermal design and software image, so the move is deliberate rather than forced. For harsh sites the rugged Jetson computers in our range are the usual starting point.
