What if a USB keypad could speak the language of your lighting software?

OSC-KEYPAD-ONYX is one example in WIZnet’s The Connected Edge:

• ESP32-S3 reads the USB keypad’s HID events.
• Firmware maps those inputs to OSC commands.
• W5500 provides the Ethernet path for UDP messages to ONYX lighting playback.

It’s a useful pattern for a custom control interface: handle the input locally, map it to the application’s protocol, then send the command over the network.

Start with the project on printed page 9, then explore room sensing, radio gateways and other connected-edge designs in the magazine.

What changes when your next device needs both wired and wireless options?

EOE-W55 combines Espressif ESP32-S3 and WIZnet W5500 in one compact module:
- ESP32-S3 provides Wi-Fi and Bluetooth LE.
- W5500 provides Ethernet with hardwired TCP/IP.
- SPI connects the two devices.

The surrounding design still matters: plan for external Ethernet magnetics/RJ45, a wireless antenna and firmware suited to your application.

What would you build with these connection options?

A camera needs data. It also needs power.

With compatible PoE equipment, one Ethernet cable can carry both.
WIZmag’s Hybrid Network Edition explores Espressif + WIZnet camera designs, from ESP32-CAM Ethernet integration to hardware with built-in PoE.

Planning a connected camera with your team? Start on pages 6–7. Then explore the audio, robot and gateway stories for more ways to combine wired and wireless connections.

Does a useful serial device on your bench need a network connection?
One application idea: bring readings from a compatible serial instrument into a monitoring application over Ethernet.
WIZnet’s WIZ750SR carries serial data over TCP/IP and converts received network data back into serial data. Choosing the right version and configuration is part of the design.
Before connecting, check three things:
- Electrical interface: TTL, RS-232 and RS-422/485 require the appropriate hardware variant and wiring.
- Serial settings: match the device’s baud rate, data bits, parity, stop bits and any required flow control.
- Device protocol: the host application still needs to understand the commands and data format carried over the connection.
Then define the network endpoints and TCP client/server roles, and test both directions with your actual device. Plan network access controls before deployment.
What serial interface and data format would your application need to carry?

Art-Net and sACN in the same pixel controller—not an either/or choice.

On expanseElectronics’ dualETH PixelControl Gen5, the incoming protocol is selected per output. One configuration can use Art-Net for Port A and sACN for Port B.

Both outputs deliver addressable-pixel signals. The LEDs are not receiving Ethernet directly.

The product family grew out of practical theatre cable-routing problems, from balconies to moving scenery.

Inside the data path, W5500 provides wired Ethernet connectivity, while ESP8266 firmware handles the lighting protocols and generates the pixel signals.

Still choosing between an Ethernet chip and a module?

Bring your project—not just a product shortlist—to WIZnet at embedded world North America.

Tell us what you’re building, how it needs to connect and which integration requirements are still unresolved.

We can discuss chip and module options, hardware and firmware integration, and whether customization is worth exploring for your application.

A brief project overview is a good starting point.

One of the most interesting embedded networking stories is when the technology disappears into a real-world result.

This example from expanseElectronics is a good one.

dualETH PixelControl is centered on a practical venue problem:
how do you move lighting data cleanly through the network, reduce wiring pain, and get that data to the pixel fixtures where it actually matters?

That is the part we think is worth highlighting.

Instead of treating Ethernet as something only used in industrial gateways or office infrastructure, this project shows how networked control can also support stage, performance, and installation lighting.

In that flow, W5500 plays a natural supporting role by helping carry the Ethernet side of the control path before the data is turned into actual lighting output.

What makes this interesting is not just the hardware.
It is the design viewpoint:

solve a real field wiring problem
move control data over Ethernet
deliver it where the lighting system needs it
make the result useful in an actual stage environment

If you were building a lighting or live-event system, which problem would you try to reduce first: cable runs, control distribution, or fixture-side complexity?

Full story is in the first comment.

Have an Ethernet integration question that a datasheet hasn’t answered?

Let’s discuss it at WIZnet Booth 5204.

Our booth connects TOE (TCP Offload Engine) technology with new products, our wider chip and module lineup, and customization services.

For a 1:1 conversation, bring a short project overview: your host interface, firmware requirements, space constraints and the integration question you’re trying to resolve.

We’ll discuss product fit and whether customization is worth exploring for your application.

A room node with Home Assistant voice.
An Ethernet connection for serial field devices.

Two different development tasks. Two projects worth exploring.

MultiSensor-V2 builds on Carletz MultiSensor, bringing sensing, local wake-word AI and HA Assist to a W5500 Ethernet/PoE room node.

Kimage takes on a different challenge: connecting serial-based field devices to Ethernet with a two-port converter built around W55RP20.
