Hello,
I know its been a bit since your post.
I’m basically trying to do the same thing with ODESC 4.2 and AS5048A.
I have found out that you can just provide 3.3V to the 5V pin on the AS5048A and it works fine.
Do you mind to provide your example sketch? Thats the part I’m struggling with. All the pins just rush through my head
