Kindly note:

1. Boost modules or buck module indicate the operating voltage, Please do not exceed operating voltage , or it will be damaged easily !
2. Boost module output voltage can only be greater than or equal to input voltage, cannot be less than the input voltage!
3. Buck module input voltage must be higher than output voltage of 1.5V or 2V, otherwise it can not output enough power!
4. Automatic Adjustable Boost or Buck module has start voltage and limit working voltage, Please donot exceed them , or it will be damaged easily !
5. Cannot reverse polarity , or it will be short circuit, or will be born easily !
