Note:

If the voltage does not change, turn it counterclockwise 20 times for normal use (if the rotation direction is wrong, the product will burn) LC SX1308 booster module carrying SX1308 chip, its packagnig is small, and high efficiency. The output power can be adjust, maximum can arrive 28V and its interior integrate the lowest RDS internal resistance 100mΩ metal oxide semiconductor field effect transistor (mosfet), which can realize large current output of up to 2A. It widely used in 3G network products, digital products, mobile power supply,battery power supply, equipment, etc. Oscillation frequency 1.2MHz efficiency is as high as 95% Circuit has short circuit protection, overheating protection function 10k to adjust potentiometer, adjust the output voltage Maximum input voltage: DC 2-24V Maximum output voltage: DC 2-28V Switching frequency: 1.2MHz Maximum current output: 2A
