The M55281KIT VoIP development kit is based on two main board components. One is the host board which provides all of the connectors plus some keys and LEDs to show status along with a connector for the module. The module is processor specific, so in this case it uses the processor for the VoIP solution, the MCF53281. The same processor can be used for representing the MCF53721 processor. In total, the module board includes the processor, the full digital system, and has been specifically designed so that it could be used separately as a complete VoIP module that can be used in a target system.
