When the device is plugged in (using a standard usb c to usb c cable, like the one from apple) it makes a high pitched sound, this only occurs when the device is not charging a battery.
I'm having the same issue, but I'm using the SG90S—it's pretty affordable. The servo keeps making noise even after reaching the target position. I have to manually nudge it slightly to get it completely quiet. I think it’s just hitting the servo’s dead band, so it can never fully reach the target position and keeps trying to adjust.

That'a strange. My device is completely silent when it sits idle. Can you locate the sound? Could it be the servo motor?

我已经修改了代码，代码完美解决了噪音并且支持SG90S,但是如何分享此代码，我github用的还不熟悉。好像附件不支持.uf2文件
