B.1 RCM3700 Prototyping Board
The RCM3700 Prototyping Board included in the RCM3700 Development Kit makes it
easy to connect an RCM3700 module to a power supply and a PC workstation for devel-
opment. It also provides some basic I/O peripherals (RS-232, RS-485, A/D converter,
IrDA transceiver, LEDs, and switches), as well as a prototyping area for more advanced
hardware development.
For the most basic level of evaluation and development, the RCM3700 Prototyping Board
can be used without modification.
As you progress to more sophisticated experimentation and hardware development, modi-
fications and additions can be made to the board without modifying or damaging the
RCM3700 module itself.
The RCM3700 Prototyping Board is shown below in Figure B-1, with its main features
identified.
