5. INSTALLATION (HARDWARE)
5.1 Setting up Shield-Servo
Shield-Servo is designed to control 8 channels of RC Servo motor. Following steps will
guide user in using this shield.
Before connection can be made, please ensure power supply is connected correctly. In general,
DC power supply only have 2 wire which is red and black. The best practise is to obtain the
polarity and voltage by measure using multimeter.
●
Servo power indicator (MPWR) will light on if the power source is connected correctly.
●
Board power indicator (PWR) will light on if the 5V power source available.
Servo motors can be driven by power source from VM and GND. The power source will be
regulated via on board switching converter to 5V with maximum current output of 4A (peak 5A).
Yet, there is option to power the servo motor from another source, which is the 5V of Arduino
main board. But we do not recommned using the 5V from Arduino as the current is limited and
normally is only 1A max. Maybe to power one small servo is still viable and sufficient, but it is
strongly not recommended to power motor than 1 servo motor. Anyway, to utilze the power from
Arduino main board for servo motor, user need to solder a jumper (
) on the shield.
