Lynxmotion SSC-32U Servo Controller Board
Electronics Guide
Analog IO Pins
There are 8 I/O pins included on the board labeled ‘A’ to ‘H’. The row of pins on the left marked
with ‘G’ correspond to ground (normally the black wire on a three pin cable). The center row of
pins, marked with ‘5’ provides 5V output (normally the red wire). The last row of pins (no label) is
for the signal. Two of these pins can also be used for I2C, with pin A corresponding to SCL and
pin B corresponding to SDA. For I2C communication, you should also connect the GND pin, and
if the SSC-32 is powering the other I2C devices, you should also connect one of the 5V pins.
Screw Terminals
VS1 provides power directly to pins 0 to 15 (ideally 4.8V to 6V for standard RC servos)
VS2 provides power directly to pins 16 to 31 (ideally 4.8V to 6V for standard RC servos)
VL provides power to the logic controller
Be sure to connect the positive wire (usually red) to the ‘+’ and the negative wire (usually black)
to ‘-’. Ensure no loose wires contact both at the same time (causing a short circuit).
Please refer to the power section of this guide for important information.
