The PWM outputs are software configurable and for them to work you must provide the **V<sub>PWM</sub>** pin with the desired voltage between 8 and 40 VDC, you can set the period and duty-cycle by software.

### Expansion Port
The expansion port can be used to daisy-chain several Opta® Expansions and additional modules. To be accessed needs to be freed up from its breakable plastic cover and the connection plug added between each device.
