I was wondering if I am able to connect an external voltage reference of 4.096 volts to VDDA (to be used as a voltage reference for ADC) without damaging the board?

Hello William,

You should respect the values indicated on the STM32F303x8 reference manual and datasheet:

                                                  2 V ≤ VDDA = VREF+ ≤ 3.6 V

If this answers your request, please click on correct

Doesn't that exceed device maximums? Review part data sheet.
