Nextion BUZZING hello I tested with an FT114 inductance, the noise dininue a little, it is necessary to add a capacitor of at least 2200µf to attenuate on the 5V off the Nextion.I had a coil that I recuperate on the THT of a TV (Much smaller).REF L-LS 100C2 LSE. I measured it. 5.6 ohm and 12.3 mh. There associated with a capacitor of 2200µf, there is no more noise by changing the brightness.For information my connection is powered by a separate regulator.I will modify my PCB to implement correctly
