Button/Potentiometer/LED Introduction:
- Long press means the need to keep press for more than 3second.
- Button ON: Short press to turn ON or OFF output voltage. A long press is used to turn the ON or OFF screen while the voltage keeps the output.
- Button SW: Short press to switch output voltage, output current or display these parameters. A long press is used to enter or exit calibration mode.
- CV Potentiometer: Adjust output voltage. Increase the output voltage when rotating clockwise. Please rotate the CV potentiometer 10 turns counterclockwise if the output voltage cannot be adjusted.
- V LED: Red indicator. It will turn ON when displaying output voltage.
- A LED: Blue indicator. It will turn ON when displaying the output current.

Input terminal: There are three input methods:
- Method 1:Standard Type A USB Male. It can just input DC 5V.
- Method 2:Micro USB Female. It can just input DC 5V.
- Method 3:IN+ and IN- pads. It can input DC 3.5V-12.0V.
- It can only choose one input method.
- Output terminal: KF-301-2P 5.08mm blue terminal. It can output DC 1.2V-24.0V.
Note:
- USB Power Supply Module is a DC power module, So it can not connect to AC power.
- Please don’t short output.
- ’ IN-’ and ‘OUT-’ can not be connected, otherwise, the module can not support constant current output.
- Please make sure the input power is more than the load power.
- Please step down the output power if the module is hot.
- Rotate the CV potentiometer counterclockwise for more than 10 turns if the output voltage can not be adjusted.
- The output current can not keep a fixed value output. It changes with load. But output power can not exceed 3W.
