I just got my 33 BLE Sense board and would like to have it generate some audio using the DAC. It would be ideal to be able to automate the write timing with DMA as well. I looked through the board specific libraries, pin include files etc and didn't see any support for using the DAC. Can anyone provide some info?

Thanks
Library? We don't need no stinkin' library...we write our own

Hello,
Same situation for me: I've just received my Arduino Nano 33 Sense board and play a bit with the IMU, temp, pressure, etc. but I can't find any info how to use the DAC.
Did you find any solution?
Thanks

I don't have any experience with the Nano 33 BLE boards, but I suspect the claim on the product page that A0 has DAC functionality is incorrect. Likely this is just a copy/paste error from the Nano 33 IoT, which does have DAC on that pin.

Really ?!! I order this board to have this functionality coupled with the IMU sensor... If I had this info, I would have taken the Nano IoT...
Can anyone from Arduino confirm this mistake ?

I recommend that you contact Arduino Store support via this form:
