1 Introduction

The EVBnet03 board was created with the aim of providing a hardware base for a designer of

systems relying on the MMnet03/04/103/104 minimodules, allowing to realize and verify quickly

one’s own ideas. Having this in mind, the board has been designed in such a way that the user

has access to all terminals of the module which are led out to connectors. The board houses also

such peripherals as: LEDs, push-buttons, potentiometers, a LCD display, a USB interface, a 1-

Wire connector. All these elements are accessible through pin connectors, permitting their

connection with any processor port. The board has also a large prototype area which permits the

designer to connect other elements in any configuration. Due to the incision (v-cut) between the

prototype area and the rest of the board, the prototype part can be broken off. The board contains

also a power supply which relieves the user from the need to provide a regulated supply voltage.

Together with the board, we deliver source codes of the Nut/OS together with the TCP/IP stack as

well as demonstration software.

The EVBnet03 along with the MMnet03/04/103/104 minimodule can be also used in didactic

laboratories of informatics colleges and universities, illustrating aspects of co-operation of

electronic circuits with the Ethernet/Internet networks. It can be also used to build circuits realizing

thesis projects.
