The drone isn’t the hard part.
The link home is.

This Maker post looks at a Japanese engineering diary about routing Pixhawk MAVLink telemetry over LTE, 5G, and Starlink.

The real issue is not just “send data to the cloud.”

The airborne side may sit behind carrier-grade NAT, so the ground station cannot always open a session toward the drone first.

That is where WIZ-IP20 becomes interesting:
Pixhawk UART telemetry
to Serial-to-Ethernet
to IP backhaul.

Important note:
This is a design proposal / research diary, not a verified flight test.

For BVLOS telemetry, what would you solve first — NAT, latency, power, or link failover?

The RJ45 port is not just a port.

It is the module.

Usually, adding Ethernet means thinking about the RJ45 connector, Ethernet controller, networking firmware, MAC address handling, configuration, and PCB space.

WIZ-IP20 compresses that into a compact MAG-JACK form factor Serial-to-Ethernet module:
UART/SPI in,
10/100 Ethernet out,
unique MAC address included.

When adding Ethernet to an existing device, what usually hurts most — PCB layout, firmware, MAC handling, or field configuration?

The machine speaks RS232.
The sensor speaks RS485.
The customer wants Ethernet.

WIZ-IP32 is a compact dual Serial-to-Ethernet module for this kind of retrofit job:
two serial ports, 10/100 Ethernet, TCP / UDP, Modbus, and configuration via AT commands, web page, or WIZS2E ConfigTool.

The practical idea:
keep the serial device logic,
add a wired Ethernet path,
avoid turning every retrofit into a full networking project.

When adding Ethernet to an existing serial device, what usually breaks the schedule first — wiring, protocol mapping, configuration, or field reliability?

One MCU for the driver.
One MCU for the data.

This track-car build uses a CrowPanel ESP32-S3 for the cabin dash, while a Teensy 4.1 handles telemetry in the trunk — GPS, tach, logging, and a W5500 wired network path.

That split is the interesting part:
the screen stays responsive,
the telemetry stays focused.

Would you build a race dash like this with 2 MCUs, or try to keep it all on one board?

The AI gets the hype.
The control board does the work.

This STM32 Nucleo F446RE board is a hardware hub for a small autonomous vehicle platform:
motor PWM, relays, RS-485, digital I/O, RGB status, and W5500 Ethernet for wired telemetry, commands, and diagnostics.

The important split:
the STM32 handles local vehicle I/O.
Ethernet handles supervision, testing, and system integration.

What would you debug first on a vehicle board — power, PWM, RS-485, or Ethernet?

Wi-Fi is great.
Some Pico projects still need a cable.

Raspberry Pi featured WIZnet W6300-EVB-Pico2 in its Maker Monday roundup of RP2350-based boards.

The interesting part:
it is not “another wireless dev board.”
It is an RP2350 board built for wired Ethernet projects where reliability, security, and speed matter.

Project ideas mentioned in the article include low-power web servers, network monitoring, IoT data logging, and industrial devices.

Would you choose Wi-Fi or Ethernet for your next Pico project?

WIZnet W6300-EVB-Pico2 is featured as an RP2350-based board for projects requiring a wired network connection.
Raspberry Pi

Raspberry Pi’s RP2350 microcontroller chip is the brains of Raspberry Pi Pico 2 and a host of third-party boards.

Your firmware already works.
Don’t rewrite it just to add Ethernet.

WIZ-IP20 is a compact Serial-to-Ethernet module for devices that need a wired network path without turning the firmware into a networking project.

UART up to 921 kbps.
10/100 Ethernet.
TCP / UDP, MQTT / MQTTS, and Modbus modes.

Where would you use this first:
legacy machines, sensors, kiosks, or test gear?

A coin goes in.
WiFi comes out.

MoziFi Piso WiFi is a coin-operated WiFi vendo system for small shops, neighborhoods, dorms, and community spaces.

The interesting part for WIZnet:
this is not just a WiFi box. It combines coin control, MikroTik integration, admin dashboard, mobile management, and W5500 wired Ethernet for a more stable network path.

Would you run a system like this in a store, dorm, apartment, or community space?

Can an Arduino stack replace a broadcast CCU rack?

TallyCCU Pro is an open-source build for Blackmagic camera control over SDI, vMix tally integration, web browser control, and Bitfocus Companion workflows.

The interesting part for WIZnet:
W5500 Ethernet is not just “network access” here. It helps the Arduino handle multiple live production paths — web UI, real-time sync, Companion TCP, and vMix tally.

Would you trust this first in a small studio, school broadcast room, church livestream, or only on a test bench?

A tiny board playing telephone operator.

This project turns an ESP32-S3 into a lightweight SIP registrar/proxy: phones register, call setup gets routed, and the voice stream can go directly between endpoints.

With W5500 Ethernet / PoE, it becomes a small wired VoIP signaling box - useful for labs, intercom experiments, classrooms, or temporary local calling networks.

Where would you test this first: lab phones, intercoms, field comms, or VoIP education?
