I've got a eachine PDB and it makes a weird hum noise (sound) when I plug my FPV gear on it, if I unplug the nosie disappear.
Same happened before with my Matek PDB from banggood, I thought it was that PDB, but now it's happening again on this eachine one too.
where is the noise coming from? LC filter? or voltage regulator?
