B.4.3 Other Prototyping Board Modules and Options
With the RCM3100 plugged into the MASTER slots, it has full access to the RS-232 trans-
ceiver, and can act as the “master” relative to another RabbitCore RCM3000, RCM3100,
or RCM3200 plugged into the SLAVE slots, which acts as the “slave.”
An optional LCD/keypad module is available that can be mounted on the Prototyping
The RCM3100 has a 2-channel quadrature decoder and a 10-bit free-running PWM
counter with four pulse-width registers. These features allow the RCM3100 to be used in a
motor control application, although Rabbit Semiconductor does not offer the drivers or a
compatible stepper motor control board at this time.
The Prototyping Board has a header at J6 to which a customer-developed motor encoder
may be connected.
Figure B-6 shows the motor encoder pinout at header J6.
