Analog Inputs Header
at header J3 on the Prototyping Board. These analog signals are connected via attenuator/
filter circuits on the Prototyping Board to the corresponding analog inputs on the Rabbit-
Core module.
RS-232
ing Board at header J4. A 10-pin 0.1" pitch header strip installed at J4 allows you to
connect a ribbon cable that leads to a standard DE-9 serial connector.
Current Measurement Option
bottom side of the Prototyping Board and install a 1 × 2 header strip from the Develop-
ment Kit to allow you to use an ammeter across the pins to measure the current drawn
from the +5 V supply. Similarly, you may cut the trace below header JP2 on the bottom
side of the Prototyping Board and install a 1 × 2 header strip from the Development Kit
to allow you to use an ammeter across the pins to measure the current drawn from the
+3.3 V supply.
Backup Battery
battery backup for the RCM4400W data SRAM and real-time clock.
NOTE: No analog signals are available on the Prototyping Board with the RCM4400W
RabbitCore module installed since no analog signals are present on the RCM4400W’s
header J1.
