USRIoT: Wiznet W5500 SPI to LAN Ethernet TCP/IP Module - USR-ES1

W5500 Ethernet Module uses the WIZnet W5500 network interface chip to provide a cabled connection to a network. The W5500 has very good library support for most microcontrollers. The Arduino, Teensy and other Arduino compatibles can use the standard Ethernet.h library included with the IDE.

The module operates at 3.3V, but the I/O is fully 5V tolerant, so it can be directly interfaced with 3.3V or 5V MCUs without the requirement for additional level shifting hardware.

Specifications:

• WIZnet W5500 Ethernet controller
