This repository should serve as a guide to everybody who wants to study software and hardware for embedded systems but doesn't know where to start.

USB 3.2 Gen 1 4-port hub based on TI TUSB8044A. 6-layer impedance-controlled PCB with USB-C cold-socket compliance, hardware power sequencing, and no MCU.

Open Agent Skill for PCB design, review, deterministic calculations, DFM, and fabrication release. Works with Codex, Claude Code, KiCad, and EasyEDA/嘉立创EDA.

End-to-End Software Framework for Emulating Signal Processing Pipelines

Temperature-controller PCB design exercise documenting sensing, control, power, and output-interface implementation.

This portfolio showcases my previous work in PCB design and fabrication. It includes pictures of various PCBs that I have designed and fabricated using Eagle PCB tool.

A simple framework of N:N face retrieval system, combined with embedded hardware to explore something about edge computing

This repository contains the latest version of my motor driver design project. My role in the project included reverse engineering a Cytron 10-A motor driver, redesigning the driver circuit using Eagle PCB tool, and designing multiple versions to improve the design.
