The Rockpro64 boards emit a buzz noise (audible only at some centimeters), this is probably due to the converters. However. there is no noise at all on the rock64. Then, I am wondering if it is not due to 12V instead of the 5V for rock64. Is there a reason for this choice ? reduce current ?
Powering with GPIO 5V does not reduce the noise
