+ | |||
+ | ====Usage of the UniPi 1.1's analog output==== | ||
+ | |||
+ | Analogue output on the UniPi 1.1 functions as a voltage regulator, requiring a voltage (connected to the AOV) and a ground (connected to the AOG). | ||
+ | |||
+ | Upon connecting the voltage, please check if the output voltage is set properly using the onboard trimmer. If not, the output voltage will not correspond with the required value. | ||
+ | |||
+ | For the output voltage setting, we recommend the following steps | ||
+ | - Connect a voltage source and ground | ||
+ | - Set the required output voltage through a control software of your choice, or by using the Pulse-Width Modulation (PWM) firmware function | ||
+ | - adjust the output voltage using the onboard trimmer and match it with the required voltage | ||

+ | An example of a 12V voltage connected to the AOV. The ground is connected to the AOG. The AOV then serves as a connector generating a positive voltage from the analogue input, which is routed to the AI1+. Thanks to this connection the user can read analog output value directly from the analog input. | ||
