Charge indicator
Overcurrent protection
Undervoltage protection function: input voltage is lower than 2.5V
IN+: Input Postive
IN-: Input Negative
Out+: Output Postive
Out-: Ouput Negative

Please note that:
This module is the fixed 5v output. If you need to adjust the output, please DIY the resistor R1, R2. [(R1+R2)/R2*0.6= VOUT]

Some applications:
DIY a mobile power, able to achieve a single lithium battery or two ordinary battery boost to 5V to charge the phone or PSP devices.
Front of a system power supply:due to the volume or other factors limit can only use a single lithium battery 3.6V
Note:Do not support the identification resistor products, such as Apple products

Package Include:
1x DC Boost Converter
