There is electrical humming sound coming from wemos D1 mini v2 module. we are using 5v 3A power supply connected to 5v input pin. I suspect its the power input which cause sparking/humming sound. Although there is no heating of device as such.

What is the recommended current supply for D1 mini module. will it harm module in long run?

@girish0002 a humming sound points to a defect in the supply controller chip or better the coil which is used. Replace the board with an original. When you are using a clone then that's normal. Much cheaper chips they used on clones. What do you think where the price difference come from?
