Topic: Arduino Due BR1 AVREF AREF (Read 616 times) previous topic - next topic


Does anyone know what BR1 is supposed to do on the Arduino Due?

I see people recommend de-soldering (BR1). However I see no one mentions what exactly it is intended to do or how it is supposed to work. It appears to be a simple voltage divider between the 3V power supply and a voltage reference from the connector.

I imagine if you want to use it for a reference signal that the voltage divider has to be configured between the 3V supply reference and the input voltage?

Or are these supposed to be capacitors for filtering AREF before it gets to AVREF?

Do the two resistors in BR1 have a resistance value? The schematic doesn't label them....
