Product Description
Aluminum medium Case Programmable Smart Robot Servo TTL SCS20
The SCS20 is a multipurpose UART BUS robot servo designed for use with Arduino.
The unit can work in both servo mode and wheel mode.
The servo mode can be wired together in robots to control limbs and set them at specific angles.
The wheel mode is intended for wheel-type operations.
The SCServo can give feedback on the values of position, temperature, load, speed
and input voltage, as well as having the ability to set parameters such as speed of rotation,
max. output torque, operating voltage limit,
operating temperature limit, etc.

SCServo can work at servo mode and wheel mode.
The servo mode can be used to multi-joints robot since the robots can be controlled with specific angles. (The factory default settingis servo mode)
The wheel mode can be used to wheel-type operation robots since motors of the robots spin infinitely. (If wheel mode is available you need to program the value of position limitation the both are 0.)
If you want to reprogram servo, you need to download the PC software (SCServo_Debug), and to connect SCPC-2(Serial Control Programming Card) between servo and PC.
More about SCServo_Debug and SCPC-2 introduce please reference its instructions.
SCServo has a unique ID number to identify on BUS network.
The range from 0 to 253 (0xFD) can be used (The factory default settingis ID 1), and, especially, 254(0xFE) is used as the Broadcast ID. If the Broadcast ID is used to transmit Instruction Packet, we can command to all SCServo.
After programmed servo ID, to be best way is written it on the sticker of servo. If not, maybe you will forget the ID when you programmed many servos.
SCServo have kinds of baud rate available.
The baud rate from 38400 bps to 1M bps can be used.
They are 38400, 57600,76800,115200,128000,250000,500000,1000000. (The factory default setting is 1000000 bps)
SCServo can feedback the value of Position, Temperature, Load, Speed and Input Voltage.
Also we can reprogram the speed of rotation, the max output torque, operating voltage limit, and operating temperature limit etc.
SCServo is easy to be controled by Arduino.
SCServo needs to have a TTLinker connect to between Arduino and SCServo.
If not please reference Connection to UART.
TTLinker is a signal conversion board. Arduino needs to convert its UART signals to the half duplex type and through TTLinker connect to SCServo. Also TTLinker have more interface used to kinds of sensor and compatible with Arduino.
