Ethernet and PoE Shield - Ethernet module with W5500 chip for Arduino

UART-RS485 converter module. It enables communication of Arduino boards with industrial modules. DFRobot DFR0259

The CAN-BUS Arduino Shield v2.0 can be stacked on an Arduino UNO, Arduino Leonardo or Arduino MEGA board. The shield integrates an MCP2515 CAN-BUS chip on the shield and has a CAN-BUS transceiver function. With an on-board DB9 and CAN-BUS connector you can choose a suitable port according to your host device. There is also an integrated MicroSD socket for data storage. DFR0370

Expansion board based on the Wiznet W5200 Ethernet chip. It allows you to easily connect the Arduino to the Ethernet network. DFRobot DFR0272

Shield for STM32 series Nucleo, XNucleo and Arduino series for communication via RS485 and CAN interfaces (CAN is only available for Nucleo and XNucleo plates). Shield is based on MAX3485 and SN65HVD230 systems

The Arduino Ethernet Shield 2 allows an Arduino Board to connect to the internet. It is based on the Wiznet W5500 Ethernet chip. The Wiznet W5500 provides a network (IP) stack capable of both TCP and UDP. There is an onboard micro-SD card slot, which can be used to store files for serving over the network. It is compatible with the Arduino Uno and Mega
