This DC –DC step down module accept DC voltage up to 40V and output stabilized 5V and 2A current. It has a digital display so you can monitor the input voltage. The 5v output can be either connected by wire or USB port. The DC-DC step down converter has a LED indicator and two buttons one for the monitor and the other for the output power delivery. The voltage display monitor can be calibrated for better measurements accuracy.
