5V To 3.3V DC-DC Step Down Power Supply Buck Module AMS1117 800MA Automatic Adjustable Boost Board Start Limit Voltage
 
 
Description:
1: input: 4.5 V DC - 7 V (input voltage must be wining the to the output voltage high 1 V above.)
2: the output: 3.3 V, 800 mA (the load current can \'t wining 800 mA)
3: PCB size: 8.6 * 12.3 mm
 
Attention:
1: the Boost modules or buck module indicate the operating voltage, both Please donot exceed operating voltage, or it will be on easily!
2: the Boost module output voltage can only be greater than or equal to the input voltage, always be less than the input voltage.
3: Buck module input voltage must be who the output voltage of 1.5 V or 2 V, otherwise it can not output the enough power!
4: Automatic Adjustable Boost or Buck the module from the start voltage and limit the working voltage, both Please donot exceed them, or it will be on easily!
5: always reverse polarity, or it will be short circuit, or will be born easily!
