This module is shorted by D+D- by default, which is compatible with most mobile phone charging, and reserves the installation position of various mobile phone identification resistors. , If you need to add identification resistor, please cut the wire connecting D+D-
6. Purpose: Ultra-wide input voltage, can be used for automotive, battery car, motorcycle, used to monitor battery voltage, timely grasp the battery status, can be used for various voltage measurement purposes
7. Note: The power module will become hot during normal use. If you are aware of this heat or are sensitive to heat, handle it carefully.
8. Weight: 13G
9. Dimensions: 58x21x10mm

Module Performance and Highlights:
1. The output capacity of 5V/2A (Note: When the input voltage is 6.5~40V, the output voltage of 5.0V can be stabilized)
2. With reverse connection protection, reverse connection will not burn
3. With over-current and over-temperature protection
4. With USB power indicator
5. With wiring terminals, easy to access the line
6. High efficiency, low ripple

Form Instructions:
After the module is turned on, the voltage can be detected in real time. When you need to charge mobile phones, iPads, MP3s and other digital products, simply touch the output enable button. At this time, the USB power indicator lights up and the USB outputs 5.0V voltage; When you need to turn off the digital tube, touch the low power button, and the module enters the ultra-low power standby mode, and the USB output is also turned off accordingly.
