( Ultrafire )Rechargeable Li-ion Battery( 5000 mAh -3.7 V ) LM358 The output is digital signal

The output is digital signal so it is easy to interface with any microcontroller such as Arduino Uno

and complementary nQ and nQ outputs

It basically allows shifting levels between a TTL signal (0 - 5 V) and a RS232 signal (15 V -  -15 V)

4V - Output 12V 1
