PiXtend V2 -L- Hardware Manual
6.6. Special Inputs and Outputs
Some inputs and outputs of PiXtend V2 -L- have special functions.
The functions and the associated possibilities are described in detail in the following. See
the PiXtend V2 -L- software manual for software configuration and usage information.
6.6.1.PWM / servo-outputs
The six PWM outputs are located on the 6-pin connector between the digital outputs and
the PiXtend power supply. On these special outputs either pulse-width-modulated (PWM)
signals with adjustable frequency and duty cycle can be output or RC servos can be
connected directly.
