Just connect 2 servos to S1 and S2 (3 pins) Usual colors for servos: Power: Red Ground: Black, Brown Signal: Yellow, White, Orange, Gray, OTHER color

When using the servo motors, and only when using the servo motors, the driver will switch the clock frequency to 50Hz. This may cause some flickering on the LEDs when dimmed. Also, the DC motor may jitter. Adding a 470uF capacitor in parallel with the motor will help in the jitter.
