Button/Potentiometer/LED introduction:
1.ON/OFF Button: Short Press to select whether output . Long press (more than 3second) to restore default settings.
2. IN/OUT Button: Short Press to switch display input voltage or output voltage. Long press to switch display output current or output power.
3. CV Potentiometer: Adjust output voltage. clockwise?Increasing.
4. CC Potentiometer: Adjust output current. clockwise?Increasing.
5. ON LED: Green LED, Output indicator.
6.CC LED: Red LED, Constant current output indicator. when the load current reaches the set current , CC indicator will turns ON.

Conversion rate: about 88%
Soft start: Yes, (a large power load module may fail when it is started)
Working frequency: 180KHZ
Protection:Input reverse connection protection,Output stop the current from feeding back protection,Output short circuit protection,Input undervoltage protection.
Diameter of mounting hole: 4mm
Weight:46g
Size: 2.59"x 1.89"x 0.79"
Package Include:1x DC buck boost converter Module LCD display
Attention?
1.IN- and OUT- must not be short circuit, otherwise the CC function will be invalid.
2. Please ensure that the power of the power supply is greater than the power required by the output load!
3.The input voltage should be over 8V ,if Full-load output .
4.when the input voltage is 5V, you can normally achieve buck-boost, but the voltage and current measurement is inaccurate; less than 4.7V, under voltage protection will be activated
