Method Of Use:
Input mode : VIN input positive level , GND input negative
Output : VOUT output positive level , GND output negativetive
Maximum output current: maximum output current = 3 / (input voltage - output voltage)
Input voltage: 4.5V-40V (the highest measured limit can reach 40V)
Adjustment mode: connect the input power supply first(between 4.5V-40V), then use the multimeter to monitor the output voltage and adjust the potentiometer (generally turn the booster clockwise, reverse the buck)
Tips:

Please adjust the required voltage with no load is applied when adjusting the voltage.
