When the Servo Power Select Jumper is applied, the servo is powered by internal 5V.
When the Servo Power Select Jumper is not applied, the servo is powered by external power source.

Motor Control Pin Jumper
Applying the Motor Control Pin Jumpers will allocate Pin 4,5,6,7 for motor control.
Removing the jumpers will release the above Pins.
¾
Wireless Select Jumper
Applying the Wireless Select Jumper will allow the controller communicate via its wireless module such
as APC220. If no wireless module is plugged, this jumper does not make any difference.
Removing the jumper will disable wireless module and allows the sketch to be uploaded.

Arduino IO Expansion Board
To support RS485 interface or drive 4 motors, IO Expansion Board is available.
This Arduino compatible I/O EXpansion Sheild is intelligently designed to facilitate an easy connection
between an Arduino board (e.g. Arduino Duemilanove) and other devices such as sensors and RS485
devcices. In essence, it expands an Arduino controller's Digital I/O and Analogue Input Pins with Power
and GND. It is compatible with Arduino Mega and is a perfect companion of Arduino Dumilanove
(Atmega168 and Atmega 328).
