PCIe Switch Expansion for Antmicro Baseboard for NVIDIA Jetson Orin

Copyright (c) 2026 Antmicro

Overview

This project contains open hardware PCB design files for an expansion board compatible with Antmicro's Baseboard for Jetson Orin. The design includes a PCIe 3.0 switch that expands the number of available PCIe ports by connecting multiple PCIe endpoint devices to a single PCIe root complex. The expansion board includes an OCuLink Connector and two M.2 (key-M) slots intended for connecting additional storage solutions with optional RAID support. Both M.2 slots support 2280 and 2242 M.2 NVMe drives. The design files were prepared in KiCad 10.x.

Key features

• Accessory compatible with expansion connector located on Antmicro Baseboard NVIDIA Jetson Orin
• Supports for 2280 and 2242 M.2 NVMe drives
• 1x M.2 key M PCIe x2 slot
• 1x M.2 key M or 1x OCuLink Connector PCIe x2 (multiplexed lane)
• 100 x 60 mm (3.94 x 2.36 inch) PCB outline
