LM317 with LED

Features:
Adjustable regulator module with LED display.
2A or less can be loaded, AC or DC voltage input.
The output voltage is 1.25V-28V DC continuously adjustable, versatile for DC board.
Using double adjustment potentiometer to ensure good contact, effectively protect the load.
Notice:
The minimum differential between input and output is 3V;
the input must be higher than the output voltage above 3V to be regulated.
Buck, not boost, when input 5V output 1.25-2V, not 6V.
