DC-DC Converter 3V to 5V 1A Step Up Boost Module with USB for Arduino Phone MP3 MP4 QS-0305-3W
Module uses the Taiwan production boost chip, high efficiency (up to 92%), plus built-in over-current protection chip, can be more good to protect the module and use the device after the class.
Module with undervoltage protection, undervoltage protection into state below 2.5V, can be more better protect the battery, to avoid excessive discharge.
Module can modify the fixed resistor adjusts the output voltage can be adjusted up to 12V output, but to ensure that the output power of less than 5W.
This module uses multilayer ceramic capacitors as main filter capacitor, the output ripple can be as low as 20mV (5V1A output case)!
This module uses a standard USB interface, you can use all universal USB charging mobile phones, MP3, MP4 and other equipment, the perfect support for IPHONE and other mobile phone.

DIY a mobile power supply, then only need to enter a battery-powered, you can output 5V voltage for your phone, MP3, MP4, PSP charger, very simple and convenient.
In order to power your electronic devices when your device needs 5V power supply, when, however, only the section you are now in the hands lithium battery-powered, with our step-up to this module can be directly 5V, solve your problems.
When you do a project when the input battery-powered (1-5V) time, and your system board and requires a 5V regulated power supply, then you choose this module we will be your best choice, debugging can not work directly on the machine, easy to achieve efficient high-power boost.
