Arduino Nano 33 BLE Interupt Pins

Hi there,

I have recently purchased an Arduino Nano 33 BLE for a project. I am intending to use encoders with my project and as such want to use Interupts however I am struggling to find which pins are able to provide that functionality. Is anyone able to advise which pins can be used? Also I would like to be able to tell from the schematic for future projects

Thanks very much


I’m trying to port some code which uses encoders from a nano to a nano 33 BLE. I’m getting freaky results in some areas, but the reading of encoder interrupts is working fine. The pins are the same as the regular nano i.e. 2 and 3.
