Original author: DCC-EX (source: https://github.com/DCC-EX/CommandStation-EX) ## Article ## CommandStation-EX — Open-Source DCC Command Station with W5500 Ethernet ### Introduction This project is an open-source **DCC command station firmware** called **EX-CommandStation (CommandStation-EX)** from the **DCC-EX** team. It turns an inexpensive microcontroller board (typically an **Arduino Mega**) plus a motor shield and a **WIZnet W5500-based Ethernet board** into a fully featured, LAN-connected **digital command station** for model railroads. With this firmware you can: - Drive a whole home or club layout in **NMRA DCC** - Control it from **phones and tablets** (Engine Driver, WiThrottle, ThrottleCard, web throttles) - Integrate with **PC software** (JMRI, Rocrail, etc.) - Script automation and layout logic with **EX-RAIL** - And do all of that over **USB, Wi-Fi, or Ethernet (via W5500)**. **What is DCC?** DCC (Digital Command Control) is the NMRA standard for digital control of model railroads. Instead of varying the track voltage like in analog DC, the rails carry a **constant-voltage digital signal**. Each locomotive has a **decoder** with its own address and listens only to the packets meant for it, so you can independently control speed, direction, lights, and sound for multiple trains on the same track. --- ### Overview — What CommandStation-EX Provides ### ![](https://maker.wiznet.io/upload/ckeditor5/1071068137%5F1764333498%2Epng) At a glance, CommandStation-EX is: - A **full NMRA DCC command station firmware** - Running on: - Arduino Uno / **Mega 2560** (the common and recommended baseline) - Arduino Nano Every, ESP32, some STM32 “Blue Pill”-class boards, Teensy, and more - Connectable via: - USB serial - Wi-Fi (ESP8266/ESP32 expansion) - **Ethernet**, using W5500-based boards: Arduino Ethernet Shield 2, WIZnet WIZ850IO, Nano Ethernet Shield, etc. - Speaking two key protocols: - **DCC-EX Native Commands** — text commands like `<1 MAIN>` (track power ON), `` for speed/direction, `` for CV operations - **WiThrottle Protocol** — used by Engine Driver, WiThrottle, ThrottleCard and many other throttle apps - Integrating with: - Engine Driver / WiThrottle / ThrottleCard - EX-WebThrottle and EX-Toolbox - JMRI, Rocrail, and other DCC tools On top of that, the ecosystem includes: - **EX-RAIL** — a small scripting language/DSL for layout automation (shuttles, loops, signals, lighting, sound, etc.) - IO expansion and helpers (EX-IOExpander, EX-Turntable, EX-FastClock, etc.) In other words: **one open-source firmware, plus a handful of off-the-shelf boards, gives you a complete digital command station platform**. --- ### Project & Team — Who Is DCC-EX and Where Are They Active? #### The Project DCC-EX describes itself as an: > “easy-to-use, affordable, do-it-yourself, open-source DCC/DC solution” It started from Gregg Berman’s original **DCC++** but has since grown into a full ecosystem: - **EX-CommandStation** (this project) - **EX-RAIL** automation - **EX-WebThrottle**, **EX-Toolbox** (Android tool app) Plus multiple hardware reference designs and add-ons. The core team is a group of **volunteer programmers and electronics engineers**, with an expanded group contributing documentation, hardware designs, testing, and support. #### Where They Hang Out **1. Discord — the main hub** - On the DCC-EX site, Discord is explicitly listed as the **preferred support and community channel**. - Multiple language channels (English, German, French, etc.) handle: - New build questions - Wiring and motor shield choices - EX-RAIL scripting help - Ethernet/Wi-Fi networking issues And most questions get answered within hours. ![](https://maker.wiznet.io/upload/ckeditor5/1071068137%5F1764333692%2Ejpg) ![](https://maker.wiznet.io/upload/ckeditor5/1071068137%5F1764333718%2Ejpg) Repo: **2. Facebook groups** - The “**DCC-EX, DCC++, and Arduino Model Railroading**” group is a semi-official hub for sharing builds, problems, and success stories. ![](https://maker.wiznet.io/upload/ckeditor5/1071068137%5F1764333828%2Ejpg) **3. YouTube** - The **DCC-EX YouTube channel** publishes how-to videos for EX-CommandStation, CSB1 ready-made hardware, and EX-RAIL. - Independent channels have produced popular videos like **“Amazing Digital Controller for Under £50”**, showing a DCC-EX build as a fully capable command station for under £50. Many users discover DCC-EX through these videos and then join the Discord/Facebook communities. ![](https://maker.wiznet.io/upload/ckeditor5/1071068137%5F1764333864%2Ejpg) [Embedded media](https://www.youtube.com/embed/jv_xfwLZJd8) **4. TrainBoard DCC Forum** - On their “About” page, DCC-EX explicitly lists the **TrainBoard DCC++ Forum** alongside Discord as a place where you can “seek us out”. - TrainBoard’s DCC forum has numerous threads tagged for **dcc++ex**, covering: - Quick build guides for EX-CommandStation - Static IP questions and Ethernet issues - Booster and power section design - Turnout wiring and running without a dedicated programming track - Other blogs and forums often say things like “for deeper discussion, see the threads on TrainBoard and the documentation on dcc-ex.com,” which shows how much the TrainBoard content amplifies the project. ![](https://maker.wiznet.io/upload/ckeditor5/1071068137%5F1764333918%2Ejpg) #### Influence & Ecosystem Impact - **JMRI** lists **EX-CommandStation** as a supported command station, with dedicated connection instructions (USB, Wi-Fi, Ethernet). - New hardware, like the **ThrottleCard** handheld throttle, explicitly supports **WiThrottle + DCC-EX Native** protocols — i.e., DCC-EX is treated as a first-class citizen alongside traditional vendors like Digitrax or NCE. - Blogs and technical sites (e.g., loco.engineering, LWN’s coverage of Everything Open 2023) present DCC-EX as a flagship example of open-source model railroading, often highlighting that you can build a full-featured system for ~€60–70. All together, DCC-EX is no longer “just a GitHub repo”; it is a widely recognized **DIY DCC platform** that influences how newcomers think about building their own command station. --- ### How It Works — Architecture & Data Flow ![](https://maker.wiznet.io/upload/ckeditor5/1071068137%5F1764334287%2Epng) #### Hardware & Timer HAL To support many MCUs, EX-CommandStation uses a hardware abstraction layer: - Separate timer/interrupt implementations such as `DCCTimerAVR`, `DCCTimerSAMD`, `DCCTimerSTM32`, `DCCTimerESP`, `DCCTimerTEENSY`, etc. - IO expansion and devices (sensors, servos, sound modules, LEDs) are abstracted via `I2CManager_*` and `IODevice*` classes, which makes it easy to tie them into EX-RAIL scripts and peripheral projects like EX-IOExpander or EX-Turntable. #### DCC Signal Engine & Track Management Core DCC logic lives in modules such as `DCC.cpp`, `DCCWaveform.cpp`, and `TrackManager.cpp`: - Generating NMRA-compliant DCC waveforms (preamble, bit timings, packet formats) - Controlling main and programming track power - Service mode programming (CV read/write) and Ops mode programming - Handling track/section mode (DCC vs DC) and block management #### Protocol & Network Layer EX-CommandStation understands two main text-based protocols: **1.DCC-EX Native Commands** - Human-readable ASCII commands in angle brackets. - Examples: - `<1 MAIN>` — turn main track power ON - `<0 MAIN>` — main track OFF - `` — set loco address 3 to speed 45, forward - `` — write CV 5 = 128 - Used heavily by EX-WebThrottle, EX-Toolbox, and tools like JMRI’s DCC++ over TCP. **2.WiThrottle Protocol** - The widely used protocol for throttle apps such as Engine Driver, WiThrottle, ThrottleCard, etc. - Handles: - Hello/handshake, client identity - Throttle acquisition/release - Speed, direction - Functions (lights, sound, smoke, etc.) - Turnout and route commands No matter whether the client connects via **USB**, **Wi-Fi**, or **Ethernet**, what ultimately flows into the firmware is one of these **text command streams**. Ethernet — and specifically **W5500** — is “just” a transport for them, but it’s a very important one. --- ### Ethernet & W5500 — What Flows Over It and Why It Matters ![WIZ850io](https://wiznet.io/files/attach/product/WIZ850io.png) #### Supported W5500 Hardware ![Arduino Ethernet Shield 2 – Internet Connectivity for Arduino Projects — Arduino Official Store](https://maker.wiznet.io/upload/ckeditor5/1071068137%5F1764334172%2Ejpeg)The official “Supported Ethernet Boards” list includes: - **Arduino Ethernet Shield 2** — based on WIZnet **W5500** - **WIZnet WIZ850IO** — compact W5500 module - Sunfounder Ethernet Shield - Arduino Nano Ethernet Shield The docs also state that the **only Ethernet chip that is actively tested and supported is W5500**. So in practice, **W5500 is the “official” Ethernet solution for EX-CommandStation**. #### W5500’s Role in the System You can think of W5500 as the **onboard network card + TCP/IP engine** for EX-CommandStation: - The MCU (e.g. an Arduino Mega) talks to W5500 over **SPI**. - W5500 provides **hardware MAC/PHY and TCP/UDP/IP** plus **eight simultaneous sockets**. - CommandStation-EX uses those sockets to host: - A **WiThrottle server** - A **DCC-EX Native TCP server** - Possibly web-based tools or diagnostics (e.g. EX-WebThrottle, EX-Toolbox connections) In short: **W5500 is what makes EX-CommandStation a first-class citizen on your layout LAN.** #### What Data Actually Goes Over W5500? **1. From clients to EX-CommandStation (control commands)** Over TCP connections on W5500, clients send: - **WiThrottle protocol packets** from apps like Engine Driver, WiThrottle, ThrottleCard: - Session setup and identification - Loco selection, speed, direction - Function toggles (lights, horns, sound slots, etc.) - Turnout and route control - **DCC-EX Native command packets** from tools like EX-WebThrottle, EX-Toolbox, or JMRI’s DCC++ over TCP: - Track power ON/OFF (`<1 MAIN>`, `<0 MAIN>`) - Throttle commands (``) - CV read/write (``, ``) - EX-RAIL automation triggers and layout logic events These are all **human-readable ASCII messages**, carried over W5500’s TCP sockets. **2. From EX-CommandStation back to clients (feedback/state)** EX-CommandStation also streams state back over W5500: - Track power status (ON/OFF, short, faults) - Current speed, direction, and function states for each loco - Turnout and route states - Results of CV reads and programming track operations - Automation/EX-RAIL progress and event notifications Clients use this to: - Update throttle UI displays - Refresh JMRI/Rocrail panels and track diagrams - Keep hardware throttles (like ThrottleCard) in sync with the command station **3. Multiple clients at once** Because **W5500 supports up to eight sockets**, you can typically have: - Several smartphone throttles - One or more PC tools (JMRI, Rocrail) - A web-based throttle or diagnostics tool all connected concurrently to the same EX-CommandStation over the same W5500 Ethernet interface. **One-line summary of W5500’s role:** > W5500 turns EX-CommandStation into a LAN-connected control hub, where multiple throttles and tools exchange WiThrottle and DCC-EX Native commands with deterministic, wired reliability. --- ### Why This Project Matters (and Why It’s a Strong UCC) **1.A de-facto standard DIY DCC command station** - Many “build your own command station for under $50/£50” guides now default to **DCC-EX + Arduino + motor shield (+ optional W5500 Ethernet)**. - It’s often recommended as a **first DCC system**: start with DCC-EX, then later choose whether you even need a commercial system at all. **2.Community-driven feature loop** - MRH, TrainBoard, and other forums note that ideas posted in the **Discord “Suggestions” channel** have become actual features in the firmware. - That makes the DCC-EX team not just implementers, but **influencers of the broader DCC ecosystem**, especially around open protocols and automation. **3.From a WIZnet viewpoint** - W5500-based boards (Arduino Ethernet Shield 2, WIZ850IO, etc.) are explicitly documented as the **officially supported Ethernet hardware** for EX-CommandStation. - In practice, that means W5500 is often the **default Ethernet chip** in home and club layouts using DCC-EX — not in a toy example, but in systems that run sessions and operations nights. - For WIZnet makers, this is a great real-world reference for how W5500 can be used as a **multi-client, TCP/IP backbone in a live control system**, not just in one-off IoT demos. --- ### Quick Start Checklist If you want to replicate a typical CommandStation-EX + W5500 setup: **1.Hardware** - Arduino Mega 2560 (recommended) - Supported motor shield (per DCC-EX docs: e.g. L298-based shields) - One of the supported **W5500 Ethernet boards**: - Arduino Ethernet Shield 2 - WIZnet WIZ850IO (or a Nano Ethernet Shield with W5500) **2.Firmware install** - Download EX-CommandStation from `DCC-EX/CommandStation-EX` releases - Use the **EX-Installer** or Arduino IDE to flash the firmware **3.Ethernet config** - Follow the “Supported Ethernet Boards / Ethernet Connection” sections in the docs - Choose DHCP or static IP - Set hostname and ports if needed - Ensure your router and firewall allow the chosen ports **4.Client integration** - On PC: configure **JMRI** to connect to EX-CommandStation via USB or Ethernet - On mobile: install **Engine Driver** or **WiThrottle** and connect via WiThrottle protocol - Optionally try **EX-WebThrottle** or **ThrottleCard** for different UI and hardware options --- 본 프로젝트는 **오픈소스 DCC 중앙기(Command Station) 펌웨어**인 **DCC-EX EX-CommandStation (CommandStation-EX)**를 통해, 아두이노 + 모터쉴드 + **WIZnet W5500 Ethernet 보드**만으로도 “집·클럽 레이아웃 전체를 제어하는 디지털 제어 허브”를 만들 수 있게 해주는 컨텐츠입니다. ## CommandStation-EX — 오픈소스 DCC 중앙기 & W5500 Ethernet 연동 *(Curated from DCC-EX / Project: EX-CommandStation)* ### 1. Overview — 무엇을 하는 프로젝트인가? **CommandStation-EX**는 NMRA DCC 규격을 따르는 **모델 철도용 디지털 중앙기(DCC Command Station)** 펌웨어입니다. **지원 플랫폼** - Arduino Uno / **Mega 2560(사실상 추천 기본 보드)** - Arduino Nano Every, ESP32, 일부 STM32(‘Blue Pill’급), Teensy 등 다양한 MCU **연결 수단** - USB(시리얼 직결) - WiFi(ESP8266/ESP32 등) - **Ethernet (W5500 기반)** — Arduino Ethernet Shield 2, WIZnet WIZ850IO, Nano Ethernet Shield 등 공식 지원 **프로토콜 & 클라이언트** - **DCC-EX Native Commands** (예: `<1 MAIN>` 로 선로 전원 ON, ``/``로 CV 프로그래밍 등) - **WiThrottle Protocol** (Engine Driver, WiThrottle, ThrottleCard 등 스마트폰 Throttle 앱의 표준 프로토콜) - 연동: Engine Driver / WiThrottle / ThrottleCard / EX-WebThrottle / JMRI / Rocrail 등 **고급 기능** EX-RAIL: 스크립트 기반 자동 운전(셔틀·루프 운전, 신호기, 조명, 사운드 등 제어) EX-IOExpander, EX-Turntable, EX-FastClock 등 확장 모듈 I2C·센서·서보·MP3 사운드 등 IO HAL 포함 요약하면, **저렴한 MCU 보드 + 모터쉴드 + W5500 Ethernet 보드**에 이 펌웨어를 올리면, 상용 DCC 시스템에 버금가는 **풀스택 DCC 중앙기**를 DIY로 구현할 수 있게 해주는 프로젝트입니다. --- ### 2. Project & Authors — DCC-EX 팀과 커뮤니티 #### 2-1. DCC-EX 팀은 누구인가? **프로젝트 정체성** 슬로건: *“Easy-to-use, affordable, do-it-yourself, open source DCC/DC solution”* Gregg Berman의 **원조 DCC++**를 완전히 리라이트하여, EX-CommandStation / EX-RAIL / EX-WebThrottle / EX-Toolbox 등 하나의 생태계를 구축. **구성** 코어 팀: **자원봉사 프로그래머 + 전자 엔지니어** 확장 팀: 문서·하드웨어 설계·유저 지원에 참여하는 커뮤니티 멤버들 **위상** JMRI 공식 문서의 “지원 Command Station” 목록에 **EX-CommandStation**이 포함되어 있으며, Engine Driver·ThrottleCard·Rocrail/EX-WebThrottle 문서에서도 DCC-EX를 직접 언급합니다. #### 2-2. 어디서 활동하나? — Discord / Facebook / YouTube / TrainBoard **(1) Discord – 1차 활동 허브** 공식 사이트에서 “**가장 빠르고 선호되는 지원 채널은 Discord**”라 명시. 영어뿐 아니라 독일어·프랑스어 채널까지 운영하며, 하드웨어 선정·배선·EX-RAIL 스크립트·Ethernet 문제 등 질문이 올라오면 **수 시간 이내**에 팀/커뮤니티가 답변하는 “실시간 작업실”처럼 활용됩니다. **(2) Facebook 그룹“DCC-EX, DCC++, and Arduino Model Railroading”** 그룹에서 DCC-EX 빌드 사진, 문제 해결, 신기능 테스트 결과가 꾸준히 공유됩니다. **(3) YouTube** DCC-EX 공식 채널: 설치 방법, CSB1 완제품 소개, EX-RAIL 활용 등 영상 제공. 외부 채널들: *“Amazing Digital Controller for Under £50”* 같은 영상에서, “50파운드 이하로 구축 가능한 강력한 중앙기”로 DCC-EX를 소개하며 입문자들이 이 영상을 통해 DCC-EX로 유입되는 흐름을 만들고 있습니다. **(4) TrainBoard DCC 포럼** DCC-EX About 페이지에서 **“우리 팀을 찾을 수 있는 곳”**으로 Discord와 함께 **TrainBoard DCC++ Forum**을 직접 언급합니다. TrainBoard DCC 포럼에는 `dcc++ex` 태그로 묶인 스레드가 다수 존재하며, “DCC-EX Command Station 쉬운 구축법”, Static IP / 라즈베리파이 연동, 부스터 구성, Turnout 배선, Prog Track 없이 쓰는 법 등 **실제 현장에서 나오는 질문/답변**이 깊이 있게 쌓여 있습니다. 다른 포럼·블로그에서 “DCC-EX 자세한 논의와 예시는 TrainBoard와 dcc-ex.com을 참고하라”고 직접 링크를 거는 경우도 많아, **외부 커뮤니티로의 파급력**도 상당합니다. --- ### 3. How It Works — 구조와 동작 메커니즘 > GitHub 리포지터리 구조 및 문서를 바탕으로, 실제 동작 흐름을 요약합니다. #### 3-1. 하드웨어/타이머 HAL 다양한 MCU 지원을 위해, 타이머/인터럽트 레벨이 아키텍처별로 분리되어 있습니다. `DCCTimerAVR`, `DCCTimerSAMD`, `DCCTimerSTM32`, `DCCTimerESP`, `DCCTimerTEENSY` 등 I2C 확장·센서·서보·사운드 모듈은 `I2CManager_*`, `IODevice*` 계열 클래스로 추상화되어, EX-RAIL 스크립트나 EX-IOExpander·EX-Turntable 등과 자연스럽게 연계됩니다. #### 3-2. DCC 신호 생성 & 선로 제어 `DCC.cpp`, `DCCWaveform.cpp`, `TrackManager.cpp`가 담당: NMRA DCC 파형 생성 (비트 타이밍, preamble, 패킷 구조 등) 메인/프로그램 트랙 파워 제어 서비스 모드(CV 읽기/쓰기) 및 Ops 모드(주행 중 프로그래밍) 블록/선로 타입(DCC/DC) 관리 #### 3-3. 프로토콜/네트워크 레이어 EX-CommandStation은 내부적으로 **두 가지 텍스트 기반 프로토콜**을 이해합니다. **DCC-EX Native Commands** 형식: `< … >` 형태의 ASCII 텍스트 명령 예: `<1 MAIN>` : 메인 트랙 전원 ON `<0 MAIN>` : 메인 트랙 전원 OFF `` : 주소 3 기관차, 속도 45, 정방향 `` : CV 5에 128 쓰기 역할: 선로 전원·속도·방향·펑션·CV 프로그래밍·블록/센서/IO 제어 전반. **WiThrottle Protocol** 스마트폰 앱(Engine Driver / WiThrottle / ThrottleCard 등)이 사용하는 표준 프로토콜. 기능: 연결/로그인, 기관차 주소 선택, 속도/방향 제어, 펑션/Turnout/Route 제어 등. 이 두 프로토콜은 USB(Serial), WiFi(ESP 모듈), **Ethernet(W5500)** 같은 서로 다른 물리 경로를 타더라도, **최종적으로는 “텍스트 명령 스트림”** 형태로 EX-CommandStation에 들어옵니다. --- ### 4. Ethernet & W5500 — 어떤 데이터를 주고받고, W5500의 역할은? #### 4-1. 공식 지원 W5500 보드 DCC-EX 공식 문서의 “Supported Ethernet Boards”에는 다음 보드들이 명시되어 있습니다: **Arduino Ethernet Shield 2** — WIZnet **W5500** 사용 **WIZnet WIZ850IO** — W5500 기반 mini 모듈 Sunfounder Ethernet Shield Arduino Nano Ethernet Shield 그리고 “**현재 공식적으로 테스트·지원하는 칩은 W5500**”이라고 못 박고 있습니다. → 즉, **W5500은 EX-CommandStation용 Ethernet의 사실상 표준 칩**입니다. #### 4-2. W5500의 역할 (한 줄 정의) > **W5500은 EX-CommandStation 안에서 “LAN 포트 + TCP/UDP/IP 엔진” 역할**을 수행합니다. MCU(예: Arduino Mega)는 W5500과 **SPI**로 연결됩니다. W5500이 제공하는 8개 소켓 위에서 WiThrottle 서버, DCC-EX Native TCP 서버, WebThrottle/진단 툴 등이 동시에 소켓을 열어 통신할 수 있습니다. #### 4-3. W5500 위로 오가는 데이터 **(1) 클라이언트 → CommandStation (제어 명령)WiThrottle 프로토콜 패킷** (Engine Driver / WiThrottle / ThrottleCard): - 연결 및 핸드셰이크 - 기관차 선택, 속도/방향 변경 - 펑션(라이트/사운드/연기 등) on/off - Turnout/Route 제어 **DCC-EX Native Command 패킷** (EX-WebThrottle, JMRI DCC++ over TCP 등): `<1 MAIN>` / `<0 MAIN>` : 선로 전원 ON/OFF `` : 속도/방향/펑션 `` : CV Write/Read EX-RAIL과 연동되는 자동운전 트리거 등 이 모든 것은 **W5500의 TCP 소켓 위로 흘러가는 텍스트 데이터**입니다. **(2) CommandStation → 클라이언트 (상태 피드백)** 선로 전원 상태 (ON/OFF, short, fault 등) 각 기관차의 현재 속도, 방향, 펑션 상태 Turnout / Route 상태 변경 CV 읽기 결과 / Prog Track ACK 에러 여부 자동운전(Automation) 진행 상황 등 클라이언트는 이를 바탕으로 Throttle UI 업데이트, JMRI 패널/레이아웃 뷰 갱신, 하드웨어 Throttle(ThrottleCard 등)의 표시를 동기화합니다. **(3) 여러 클라이언트 동시 접속** W5500은 8개 동시 소켓을 지원하므로, 스마트폰 Throttle 여러 대, PC(JMRI), 브라우저(웹 Throttle) 등이 동시에 접속해도 운전이 가능합니다. --- ### 5. 커뮤니티 & 인플루언서 효과 — 왜 “파급력이 있는” 컨텐츠인가? **DIY DCC 중앙기의 사실상 표준 옵션 중 하나** JMRI, ThrottleCard, 여러 튜토리얼 블로그/유튜브가 “DIY DCC 중앙기를 만들려면 DCC-EX + Arduino + 모터쉴드”를 가장 먼저 추천합니다. “50달러/50파운드 이하로 구축하는 디지털 중앙기”라는 콘셉트로 반복 소개되면서, **입문자에게 DCC-EX가 ‘첫 DCC 시스템’으로 자리 잡는 경우**가 많습니다. **커뮤니티 제안 → 실제 구현 루프** MRH 포럼, TrainBoard 등에서 “Discord의 Suggestion 채널에 올린 아이디어가 실제 기능으로 들어갔다”는 피드백이 존재합니다. 즉, DCC-EX 팀은 단순히 코드를 제공하는 수준을 넘어, **오픈 DCC 생태계의 방향을 함께 설계하는 인플루언서적 역할**을 하고 있습니다. **WIZnet 관점에서 보는 레퍼런스 가치** W5500 기반 보드(Arduino Ethernet Shield 2, WIZ850IO 등)가 DCC-EX 공식 문서에 정식 지원으로 명시되어 있고, 실제로 집·클럽 레이아웃에서 **“중앙기를 LAN에 붙이는 기본 네트워크 칩”**으로 사용됩니다. 따라서 WIZnet Maker 입장에서 이 UCC는, “W5500이 실전 모델 철도 프로젝트에서 어떤 데이터·역할을 맡는지”를 가장 잘 보여주는 사례 중 하나입니다. --- ### 6.
