DFRobot - M.2 NVMe to OCuLink Adapter for LattePanda Dev Board (PCIe 4.0 x4, up to 64Gbps)

This M.2 NVMe to OCuLink adapter converts an M.2 NVMe M Key interface into a standard OCuLink interface for high-bandwidth PCIe expansion. Based on the PCIe 4.0 x4 specification, this adapter supports a maximum bandwidth of 64Gbps and is suitable for connecting high-performance PCIe devices through OCuLink.

PCIe 4.0 x4 Bandwidth up to 64Gbps

This M.2 to OCuLink adapter supports PCIe 4.0 x4 transmission with peak bandwidth up to 64Gbps. The direct interface conversion provides a high-speed connection path between an M.2 NVMe M Key slot and OCuLink-based expansion hardware.

Supports Multiple M.2 Board Sizes

This OCuLink adapter board supports 2280, 2260, 2242, and 2230 sizes, providing flexible installation options for systems with different M.2 mounting positions and mechanical layouts.

Industrial-Grade PCB Construction

This adapter uses an industrial-grade black double-layer PCB with a 10u" immersion gold process. The PCB material is designed for high-frequency transmission while providing low resistance, high-temperature resistance, and oxidation resistance. Gold-plated fingers meet IPC Level 1 international standards.

Wide Operating Temperature and Flame Retardant Design

This PCIe adapter supports an operating temperature range of -40°C~80°C and meets a 94V-0 flame retardant rating, supporting reliable integration across a wide range of operating environments.
