Thunderbolt to PCIe Adapter

Copyright (c) 2022-2023 Antmicro

Overview

This project contains open hardware design files for an adapter board wrapping 4-lane (i.e. 4x) PCIe Gen 3.0 devices into a Thunderbolt 3 uplink. It is based on the Intel/JHL6340SLLSQ Thunderbolt controller. The design files were prepared in KiCad 6.x.

Key features

• Intel JHL6340SLLSQ Thunderbolt 3 controller
• PCIe x4 expansion slot
• On-board Step-Up DC-DC generating 12V (required by some PCIe cards)

Project structure

The main directory contains KiCad PCB project files, a LICENSE, and a README. The remaining files are stored in the following directories:

• lib - contains the component libraries
• img - contains graphics for this README
• doc - contains schematics in pdf form
