Framework OCuLink Dev Kit

The Framework OCuLink Dev Kit is a modular adapter and dock system for the Framework Laptop 16, previewed on April 21, 2026 at Framework's next-gen hardware event¹²³. It uses the OCuLink 8i interface to provide up to 128 Gbps bidirectional throughput for external PCIe devices, making the Framework Laptop 16 the first laptop to expose an 8-lane OCuLink interface²⁴. The kit enables connecting external GPUs, network cards, video capture cards, and other PCIe peripherals with very little performance penalty compared to a desktop PC²⁵.

Preview

This product has not yet shipped. Pre-orders are open with a $100 fully-refundable deposit; final per-component pricing and a firm ship date have not been announced. Framework expects to ship the kit later in 2026²⁵⁶.

The Dev Kit leverages the Framework Laptop 16's Expansion Bay, which provides an internal PCIe x8 interface originally designed for upgradeable discrete Graphics Modules². The Expansion Bay interface is identical across the Ryzen 7040 and Ryzen AI 300 FW16 models, so the OCuLink Dev Kit is backwards-compatible with both². When Framework open-sourced the Expansion Bay documentation, the community quickly developed multiple OCuLink adapter designs⁷. Framework's official kit builds on those community efforts with a polished solution².

Kit Components

Component	Description
OCuLink Expansion Bay Adapter	Drops into a Framework Laptop 16 Expansion Bay Shell and routes the PCIe interface to an OCuLink connector on the rear of the laptop24
Graphics Module OCuLink Dock	Allows re-using Framework Laptop 16 Graphics Modules externally at native performance25
PCIe OCuLink Dock	Accepts standard desktop PCIe add-in cards (GPUs, 100 Gbps network cards, video capture cards, etc.)24
OCuLink 8i Cable	The high-speed 8-lane cable connecting laptop to dock6

Design Philosophy

Framework designed the kit as a bare-bones developer kit to keep costs low⁵. Framework provides the core electronics, structural components, and reference 3D-printable enclosure designs, while users supply the GPU, power supply, and overall setup²⁵. Users can pick individual components or the full kit, and can mix and match with other OCuLink solutions already available on the market⁵.

OCuLink differs from Thunderbolt and USB4 eGPU solutions by providing a direct PCIe connection without protocol overhead, resulting in near-native performance⁴⁵. The trade-offs are that OCuLink connectors are less robust, only transmit PCIe data (no USB or power delivery), and do not support hot-plugging⁵.
