The RAK13800 WisBlock Ethernet Module extends your WisBlock system with Ethernet connectivity using the WIZnet W5100S-L chip.

It supports 10Base-T / 100Base-TX transfer speeds, multiple hardware sockets, and SPI host communication for easy integration with WisBlock Core modules.
 
With four independent sockets, internal TX/RX buffers, and low-power Ethernet management features like Wake-on-LAN (WOL) and power-down modes, the RAK13800 delivers efficient, stable, and high-performance networking for embedded IoT applications.

When paired with the RAK19018 daughter board, it also supports Power over Ethernet (PoE), simplifying cabling and deployment in remote or industrial settings.
