Analog Inputs Header
—The analog signals from the RabbitCore module are presented 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 RCM4510W mod-
ule.
NOTE:
No analog signals are available on the Prototyping Board with the RCM4510W Rab-
bitCore module installed since no analog signals are present on the RCM4510W’s header J1.
The auxiliary I/O on the RCM4510W’s header J4 cannot be used with the Prototyping Board
without modifying the Prototyping Board.
•
RS-232
—Two 3-wire or one 5-wire RS-232 serial ports are available on the Prototyping
Board at header J4. A 10-pin 0.1" pitch header strip installed at J4 allows you to connect a rib-
bon cable that leads to a standard DE-9 serial connector.
•
Current Measurement Option
—You may cut the trace below header JP1 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 +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
—A 2032 lithium-ion battery rated at 3.0 V, 220 mA·h, provides battery
backup for the RCM4510W SRAM and real-time clock.
