Lynxmotion SSC-32U Servo Controller Board
Electronics Guide
Tx Rx
The two LEDs next to the USB port provide the user with visual feedback of when data is
received (Rx) and if data is transmitted (Tx). These are only associated with communication via
the USB port and not the XBee header or serial pins.
Serial
The three pins behind the FTDI chip are Tx, Rx and GND. Commands sent from the SSC-32U
are done using the Tx pin while commands to be received by the SSC-32U are done via the Rx
pin. These pins allow you to easily send commands to the servo controller from another
microcontroller. To do so, connect the Tx pin on the microcontroller to the Rx pin on the
SSC-32U, the Rx pin on the microcontroller to the Tx pin on the SSC-32 and GND to GND.
