To maximize the availability of RCM2100 resources, the demonstration hardware (LEDs

and switches) on the Prototyping Board may be disconnected. This is done by cutting the

traces below the silk-screen outline of header JP1 on the bottom side of the Prototyping

Board. Figure B-4 shows the four places where cuts should be made. An exacto knife

would work nicely to cut the traces. Alternatively, a small standard screwdriver may be

carefully and forcefully used to wipe through the PCB traces.

Figure B-4. Where to Cut Traces to Permanently Disable

Demonstration Hardware on Prototyping Board

The power LED (PWR) and the RESET switch remain connected. Jumpers across the

appropriate pins on header JP1 can be used to reconnect specific demonstration hardware

later if needed.

Note that the pinout at location JP1 on the bottom side of the Prototyping Board (shown in

Figure B-4) is a mirror image of the top side pinout.

The

Prototyping Board provides the user with RCM2100 connection points brought out con-

veniently to labeled points at headers

J2 and J4 on the Prototyping Board. Small to medium

circuits can be prototyped using point-

to-point wiring with 20 to 30 AWG wire between the

prototyping area and the holes at locations J2 and J4. The holes are spaced at 0.1" (2.5 mm),
