I can power it from a bench supply without a problem. What kind of step-down circuit is recommended so the unit can be powered from a USB? And what capacitance should be capacitors next to the power pin ?

is it the only cause? I have tried to power the circuit from a 2A power supply and it still shows the same. The width of the traces is 30 or full copper plate at parts. GND traces are 20.
