WisBlock RAK13800 Ethernet Interface W5100S-L

The WisBlock RAK13800 is an Ethernet interface module that extends WisBlock systems with a wired Ethernet communication. Based on the WIZnet W5100S chip, this module supports 10BaseT and 100BaseT Ethernet transmission speeds and provides the option to power the WisBlock modules via an optional PoE module (Power over Ethernet). It is ideal for projects that require a reliable and fast internet connection.

The WisBlock ecosystem by RAK Wireless offers compact and modular solutions to create your own IoT LoRaWAN nodes. A variety of CPU, sensor, and IO expansion modules can be mounted on a WisBlock base board. Unlike conventional plug connections, the modules are secured to the base board with screws. This creates a secure and reliable mounting with industrial quality. Thanks to its modular and compact design, WisBlock is particularly suitable for prototype construction applications in the professional or hobby sector.
