Function

Servo Supply

Voltage

VM is one of Shield-Servo power sources. VM will supplies

power to Servo motor. Although Shield-Servo provides

protection against wrong polarity for this input, user must

ensure the voltage and polarity of connection are correct

before providing the power so that Shield-Servo can function

correctly.

GND

System Ground

Common ground for both logic operation and Servo motor

power source.

*If power is connect correctly, the PWR LED should light up.

Signal Input Pins Function Description

Definition

Function

Transmit Pin

This pin is TTL/CMOS logic (5V and 0V). Output signal

from Shield Servo transmitted using this pin. Pin available

to use is D1,D3, D11, D13.

Receive Pin

This pin is TTL/CMOS logic (5V and 0V). Input signal to

Shield Servo from arduino transmitted using this pin.Pin

available to use is D0,D2, D10, D12.

UC00A/UC

00C

Control Pin

Pin out for UC00A/UC00C/UC00C.

S1-S8

Signal Out

Output signal to drive the Servo motor. This pin is

TTL/CMOS logic (5V and 0V). Each pulse (logic

change from 0 to 1) will drive the Servo motor.
