The RCM3720 Prototyping Board comes with the basic components necessary to demon-
strate the operation of the RCM3700, RCM3710, RCM3720, and RCM3750 modules.
Two LEDs (DS1 and DS2) are connected to PF6 and PF7, and two switches (S1 and S2)
are connected to PF4 and PB7 to demonstrate the interface to the Rabbit 3000 micropro-
cessor. Reset switch S3 is the hardware reset for the RCM3720.
The RCM3720 Prototyping Board provides the user with connection points for the Rabbit-
Core module brought out conveniently to labeled points at header J2 on the RCM3720
Prototyping Board. Although header J2 is unstuffed, a 2 × 20 header strip with a 0.1" pitch
can be installed. The 2 × 20 header (Part No. 405-0016) can be purchased through our
online
store.
To maximize the availability of resources, the demonstration hardware (LEDs and
switches) on the Prototyping Board may be disconnected. This is done by cutting the
traces seen within the silkscreen outline for header J4 on the bottom side of the RCM3720
Prototyping Board. Figure B-15 shows the four traces where cuts should be made. An
®
exacto knife or high-speed precision grinder tool like a Dremel
tool would work nicely
to cut the traces. Alternatively, if safety is a major concern, a small standard screwdriver
may be carefully and forcefully used to wipe through the PCB traces.
