WIZ550WEB 개요
An embedded web server module is a self-contained computing block that hosts a TCP/IP stack plus application logic on the same PCB, exposing control and telemetry through standard web browsers. Within the broader embedded system taxonomy, the WIZ550WEB sits between a discrete MCU and a full SOM (system-on-module); it can be classified as a microcontroller module > embedded module > SOM > embedded computing platform. Its primary value is eliminating the firmware burden of implementing a TCP/IP stack on a host processor, since the W5500 offloads all TCP, UDP, ICMP, IPv4, ARP, IGMP, and PPPoE processing in dedicated hardware.
Key differentiators of the WIZ550WEB include WIZnet's hardwired TCP/IP offload (no host CPU cycles required for socket operations), 8 simultaneous hardware sockets, an integrated 32 KB buffer, 8 MB external flash for web page and firmware storage, plus 4 ADC inputs that accept 0-12 V analog signals through an on-board resistive divider. The factory firmware implements a non-OS web server with configurable I/O pages, a serial AT command interface, an SD-card backed configuration tool, and open-source reference firmware published on GitHub for developer customization.
Typical application scenarios include industrial sensor telemetry over Ethernet, building automation gateways, factory equipment web dashboards, remote relay and GPIO control, energy-monitoring data loggers, and prototype IoT bridges where a developer wants Ethernet connectivity without writing a TCP/IP stack. The 0-12 V ADC inputs are particularly useful for direct connection to industrial 0-10 V transducer outputs. The module can also serve as a fast prototyping platform for Ethernet-enabled products based on WIZnet's W5500 silicon.
When designing with the WIZ550WEB, designers should follow WIZnet's reference schematics to ensure proper biasing of the W5500's analog front-end and adequate decoupling near the RJ45 magnetics. Because the module uses a pin-header through-hole interface rather than a fine-pitch SMT footprint, integration is straightforward on a custom baseboard or even a solderless breadboard with a matching socket strip.

일반적인 애플리케이션
WIZ550WEB 적합 용도: 6 애플리케이션s: Industrial Sensor Telemetry Gateway, Building Automation Web Dashboard, Remote Relay and GPIO Control, Factory Equipment Web Interface, Energy Monitoring Data Logger, Ethernet-Enabled IoT Prototype Bridge.
Industrial Sensor Telemetry Gateway
The WIZ550WEB serves as a wired Ethernet gateway for industrial sensor telemetry in factory automation and remote monitoring. Its 4 analog inputs accept 0-12 V from standard industrial transducers, while the 16 digital I/O handle discrete signals from limit switches and relay contacts. Hardware TCP/IP offload via W5500 frees the STM32 host to poll sensors at high rates without dropping Ethernet packets. Compared with WiFi alternatives, the RJ45 wired link delivers deterministic latency immune to plant RF noise. Reference designs and example firmware are available on the WIZnet GitHub repository.
추천
Building Automation Web Dashboard
The WIZ550WEB enables building automation dashboards by serving web pages that visualize HVAC, lighting, and access-control status. The 8 MB flash holds full HTML/CSS/JS dashboards accessible from any browser, while the micro SD socket supports logging sensor history without burdening the host MCU. The 0-12 V ADC range is convenient for connecting to building management 0-10 V actuator feedback signals. Unlike cloud-dependent IoT devices, all data stays on the local LAN, satisfying privacy and uptime requirements.
추천
Remote Relay and GPIO Control
The WIZ550WEB exposes 16 configurable digital I/O pins that can directly drive relays, optocouplers, or read dry contacts for remote equipment control via web browser. This makes the module ideal for unattended equipment rooms, irrigation systems, and lighting controllers where a browser-based UI is preferred over a custom HMI. Hardware TCP/IP acceleration ensures the 8 socket limit is rarely hit even with multiple browser clients polling I/O status.
추천
Factory Equipment Web Interface
The WIZ550WEB's pin-header through-hole interface simplifies installation in custom factory equipment enclosures where technicians may need to swap modules without desoldering. Operators connect to the module's IP address through any browser to monitor machine status, accept recipe parameters, and acknowledge faults. Compared with panel-mount HMIs, the WIZ550WEB eliminates the cost of dedicated display hardware while still providing a graphical user interface.
추천
Energy Monitoring Data Logger
The WIZ550WEB can log energy meter pulse outputs via its 16 digital inputs and post data to local dashboards or upstream servers through its 10/100 Ethernet link. The SD card socket provides terabyte-scale local logging capacity, while the W5500's hardware TCP/IP stack supports periodic HTTPS posts to cloud services. This dual-role (local + cloud) capability suits substation and renewable-energy monitoring where outage-tolerant local storage is required.
추천
Ethernet-Enabled IoT Prototype Bridge
The WIZ550WEB is a fast prototyping platform for engineers building Ethernet-enabled products who want to start with proven W5500 firmware before committing to a custom PCB. The open-source firmware on GitHub provides a working web server, AT command interface, and SD-card configuration tool that can be modified or used as-is. Unlike discrete W5500 chip designs that require custom magnetics and RJ45 layout, the WIZ550WEB integrates all Ethernet PHY hardware, accelerating prototype-to-production timelines.

설계 노트
The WIZ550WEB module requires a stable 3.3 V supply for the STM32F103RBT6 host and W5500 Ethernet controller; power the module through the 37-pin header VCC pin with adequate decoupling (10 uF bulk + 0.1 uF ceramic) located within 5 mm of the header pin. Estimated: total module current draw at full Ethernet activity is approximately 200-250 mA, leaving headroom for any external sensors powered from the same rail.
The WIZ550WEB operates without active cooling in typical indoor environments. Ensure the SD card socket and RJ45 jack have unrestricted airflow and that the module is not enclosed in a fully sealed plastic housing without ventilation, as the STM32 and W5500 can each dissipate 200-500 mW under sustained SPI/Ethernet activity. Mount vertically when possible for natural convection.
When designing a custom baseboard to host the WIZ550WEB, follow WIZnet's reference schematics to preserve the RJ45 magnetics integration and W5500 analog front-end. Maintain a continuous ground plane under the module and keep the 50 ohm Ethernet signal traces away from switching power or relay traces. The 37-pin through-hole header uses 2.54 mm pitch - design pad geometry to accept standard 0.64 mm square pins.
Do not exceed 12 V on the analog inputs (A0-A3) - the on-board divider assumes a maximum of 12 V input mapped to 3.3 V ADC full-scale. Do not attempt to read 24 V industrial signals without adding an external divider. Also note that the W5500 IPv4-only stack cannot directly serve IPv6-only clients; if IPv6 is required, migrate to the W6100-EVB alternative.
Keep the SD card socket accessible in the final enclosure for field firmware updates. Route the W5500 SPI signals (SCK, MOSI, MISO, CS) as short, impedance-controlled traces with the W5500 placed within 25 mm of the STM32 host. Use 4.7K pull-ups on the W5500 interrupt and reset lines per WIZnet reference design.
