Instructions
Input and Output must be connected correctly
Conventional Constant Voltage Output BOOST Fully Integrated Solutions, Integrated MOSFET, Fewer External Components, Smaller Cos System Built-in over temperature protection, full set overcurrent protection circuit reliability, high reliability TO263-5L standard package, suitable for 30W boost inside applications.
Power (3-35 V), power indicator light, module is working properly.
Adjust the blue knob of the potentiometer (counterclockwise general impulse, buck clockwise rotation) and with a multimeter to monitor the output voltage reaches the required voltage
NOTE:

Long hours working current is recommended for use at less than 2.5 M, while adding heatsink mass (10 W output above); Because it is boosting the module, in order to ensure stable output, please keep the minimum differential 1.5 V.
