Does ard nano 33 sense have DAC ?

Just bought two Ard Nano 33 Sense; I see in Arduino specs that A0 is configurable as AI (ADC0) or AO (DAC0), but I could find no DAC in any of the block diagrams of Nordic nRF52840 or Ublox NINA B-306. So, does Arduino Nano 33 Sense have DAC or not ?

I don't know specifically about the Nano 33 Sense, so I am sorry. When Arduino talk is about analog outputs, it is usually about PWM. There is a PWM module in the block diagram of the Nordic nRF52840. For example, look near the lower left corner of Figure 1 (page 18) of https://infocenter.nordicsemi.com/pdf/nRF52840_PS_v1.1.pdf

Post a link to the exact module that you have.
