 + 
 +====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. ​
