Little notes

the function of undervoltage indicator:If voltage is large enough,the indicator is on.when the voltage is lower than 2.7V,the indicator is off and you should charge the battery,or it might be damaged.

Applications

• DIY mobile power supply:when you are on business trip or in tourism,you can prepare such a mobile power supply so that you can charge the battery of your mp3 or mobilephone with some other batteries.
• voltage adjusting:when your design needs different voltages,it will be a good choice to use this module.
• make your power supply stable:when your power supply is not stable,you can use this module to make it.
