B.1 Introduction

The Prototyping Board included in the Development Kit makes it easy to connect an RCM4000 module to a power supply and a PC workstation for development. It also pro- vides some basic I/O peripherals (RS-232, LEDs, and switches), as well as a prototyping area for more advanced hardware development.

For the most basic level of evaluation and development, the Prototyping Board can be used without modification.

As you progress to more sophisticated experimentation and hardware development, modifications and additions can be made to the board without modifying the RCM4000 module.

The Prototyping Board is shown below in Figure B-1,with its main features identified.
