Designed by Namnam in Vietnam, the ESP32 Modbus gateway is built to communicate with PLCs and industrial sensors over Modbus ...

The article is a tutorial on how to control 16 relay through Arduino microcontroller with Ethernet shield W5100.

Arduino Ethernet Shield uses an external Ethernet controller chip (W5100) that connects to an Arduino board via SPI, and provides an easy-to-use library for Ethernet communication.

You can create a release to package software, along with release notes and links to binary files, for other people to use. Learn more about releases in our docs ...

Arduino UNO SPE Shield adds Single Pair Ethernet (SPE) and RS485 to Arduino UNO and compatible boards, notably the Arduino UNO R4, via a Microchip LAN8651 SPE controller. Single Pair Ethernet relies ...

In that spirit, [Doug Jackson] shows you how to conserve the expensive Arduino board and Ethernet shield by building your own Arduino Ethernet module.

Arduino have taken the tiny wraps off of the official ethernet shield for their open-source prototyping platform, which adds network connectivity to the device. Based… ...

[Andy] needed a cheap Internet connection between a data-gathering Arduino and his home server. An Ethernet shield would suffice, but he couldn’t run CAT5 to the Arduino’s location. Wir… ...
