INTRODUCTION AND OVERVIEW

1.0 Introduction of SHIELD-Servo

SHIELD-Servo offers reliable yet user friendly RC (Radio Control) Servo motor controller to

hobbyist and students. Different with SC16A and SC08A, SHIELD-Servo is designed to control 8

independent RC (Remote Control) Servo motors simultaneously in a single board with a built in

5V 5Ampere switching regulator. Each Servo signal pin is able to generate Servo pulses with duty

cycle from 0.5ms to 2.5ms, which is greater than the range of most Servos, further allows for

Servos to operate in full range of 180 degrees. In order to get SHIELD-Servo working, an Arduino

compatible main board (Arduino/Genuino UNO, Mega, CT-UNO, CT-ARM, etc) is needed and

the interface is serial (UART). The shield also provide alternative control over 6 pin UART with

USB to Serial converter UC00A/UC00B/UC00C or other types of microcontroller. UART

interface present a flexible, fast and easy to use feature.

This Servo driver has been designed with capabilities and features of:

● New! Now comes with UC00A/UC00C/UART interface for easier communication

between the user’s circuit (or PC) and SHIELD-Servo. By using the new UART control,

user can

○ Activate each Servo independantly

○ Control position for each Servo

○ Control Servo speed

● Support up to 5A (peak) and 4A(continuous) of total current.

● Control 8channels Servo independently.

● Able to drive Servo motor from 7V to 25V with build in 5V regulator.

● Optional Position Reporting: User may request position of an individual Servo.

● 5V logic level compatible inputs.

● Independent Starting Position Command for each channel at the next start-up

● Servo pulse range 0.5ms to 2.5ms.

● UART baud rate is saved in non-volatile memory (Factory default is baud rate = 9600).
