Hello all,
I have an issue with the 5V input to the Arduino Nano. I noticed that when I power (using a power bank) my Nano via the USB port I get a clean ADC reading from my microphone but using the same power via the Vin pin I am getting noise. This makes me think there is a filter in the path. I have attached the schematics, can someone identify what that filter is?
Thanks,
Markus
