Research direction

No files, tests, or code entry points are identified. Start by checking the Wemos D1 mini v2 power-input documentation and the reported 5 V, 3 A supply, then determine whether the humming is an electrical fault or expected behavior and document the safe recommended supply guidance.

Description

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?
