Product User’s Manual – SC08A

A – Blue terminal block for servo motor power source. Please connect correct power to the

provided connector and check the polarity before plug in. Normally, rated voltage to drive

servo motors is in between 4.8V and 6V. Some may need 7.2V. It is depending on the type of

servo motor used. Over supply voltage may spoil the servo motor!

B – 8 channels of servo motor. Each channel consists of 3 header pin. Servo motor channels t

are labeled at the top. Please follow the label for connecting servo port to SC08A, ‘S’ is for

signal line.

C – Header pin to configure SC08A for expansion mode. For single board usage, a mini

jumper should be put on '1-8'. If SC08A is used in expansion, one of SC08As must be

configure to expansion board, the mini jumper should be put on '9-16'.

D – A small orange LED to indicate power for servo motor. It should illuminate if power

source is connected properly.

E – A small green LED to indicate 5V for PIC operation.

F – 4 ways header pin and connector for UART communication (using UC00A) and for user

to connect SC08A to microcontroller host or another SC08A board. Please be cautions during

making connection to this header, wrong polarity will damage servo controller.

G – Servo test button. Press the test button and the pulses generated will drive servos to the

end of position. It is useful to test if the servo controller is working.

H – 18 pin of PIC16F1827

I – Reset button for SC08A. Pressing this button will stop all pulses generation and return

SC08A to initial stage if after released. Without pulses generation, all servo connected to

SC08A will not rotate, is free run.
