This is a giant mistake, NOBODY CONNECT THE AMMETER ON THE EXIT AS IT SAYS ON THE VIDEO … IT WILL BURST !!!
Connecting the Amperimeter to the output will burst the XL4015E1 IC or Multimeter.
It appears to me one other video to promote the regulating boards, these boards solely regulate the Volts, if putting the meter in collection with the battery solely provides a most of 400mA, even with an Industrial Well of 12.5A Mean Well 12VDC.
Turning the potentiometer knob W 102 does nothing …
It sucks this board.
