MAX232 Boards are used to connect the MAX232 circuit to a prototype board. There is a Dual RS232 Driver/Receiver MAX232N provided on the board. This circuit is necessary for establishing RS232 communication. All available components are clearly marked on the board so that there is no need for additional schematics.
Ethernet Connector Boards include a 10/100 Base-Transformer RJ45 connector that enables you to easily connect your prototype board to the Ethernet network. As soon as you connect your prototype device to the Ethernet module pins, you are ready to transmit and receive data using this type of communication.
