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