Feature:
Input voltage: 2.5 V to 15 V
Output Voltage: DC 5V-20V
Maximum output current: 2A
Efficiency: 93%
(Minimum) (input-output) difference voltage when input is at (2 V and 50% of max-input-V), loading at (50% and 100% rated current)

Method of use:
The module of the IN+ and - after 2~15v, adjusting the potentiometer can adjust output voltage, output voltage is greater than the input voltage

Matters needing attention:
The input voltage should not exceed the maximum input voltage
The peak current output current no more than 2V
When the module output voltage can not be adjusted, the output voltage is always equal to the input voltage. Please adjust the potentiometer counterclockwise 10 laps or more (Let potentiometer against your chest, counterclockwise turn boost)

Package Included:
10 X MT3608 DC Voltage Regulator Board
