The subject of the thesis is an Ethernet module, designed for use in microcontroller systems. The advantages of a modular system are also presented. In the first part, the theoretical basis of internet communication is explained. We emphasize the IP addressing and the operation of the TCP protocol. In the practical part of the thesis the Ethernet module is divided into its components and their functionality is described. We have explained the design of the printed circuit board with the EAGLE software package and produced the circuit. Finally, the module was tested using various terminal softwares. From the point of view of communication analysis, we presented the practical use of a logical analyser and the Wireshark software.
