Hi!
I am using this HAT along with a Raspberry PI 5. It works smooth.
My issue comes with the analog inputs. The HAT analog inputs are "pulled up" to 3.3V through 15K resistors (see attached image).
Those resistors alters my analog signal circuitry, adding a DC voltage that I don't need or require.
Is there a way that the HAT provide analog inputs without that pullup?
Any suggestions will be welcomed.
Thank you!
Mario
