22 RabbitCore RCM2300
The RCM2300 modules have two 26-pin headers to which cables can be connected, or
which can be plugged into matching sockets on a production device. The pinouts for these
connectors are shown in Figure 5 below.
Figure 5. RCM2300 I/O Pinout
Fifteen additional connection points are available along one edge of the RCM2300 board.
These connection points are 0.030" diameter holes spaced 0.05" apart. Nineteen additional
connection points are available at locations J2 and J3. These additional connection points
are reserved for future use.
The remaining discussion is focused on the I/O points available on headers J4 and J5
because it is anticipated that most users will not use the through-hole connection points
because of their reduced convenience.
Table 1 lists the pinout configurations on headers J4 and J5. The ports on the Rabbit 2000
microprocessor used in the RCM2300 are configurable, and so the factory defaults can be
reconfigured. Table 1 lists the factory defaults and the alternate configurations.
.
Note:
These pinouts are as seen on
the Bottom Side of the module.
