Hi,
ADC range in Artemis Thing Plus is from 0-2V. It’s possible to route the internal ADC reference to the pin?
Thank you in advise
No, there is no pin that can be selected for that. The Apollo3 chip has an ADCREF pad, but most of the time only a capacitor is added to that for stability. Maybe if you add a wire to that pad it might work, but the schematic is not clear whether the pad can be accessed.
