Where is VREF pin on Dash


Is there a Vref pin for this device? I wish to use the ADC and want to feed it a clean voltage reference for the ADC comparators.

Also, what is the Voltage reference for the ADC? I assume 3.3v? thanks.


Hi @bitshift. I had a similar question and found this thread, which states that the reference voltage is 3.3V. I’m not aware of there being a Vref pin on the Dash.


There is a 3.3v pin on the Dash, you can use that as your Vref.
