Description: Feature:1. When used as UPS, SW pin should be shorted to keep the output on in real time. When the power is off, can start battery power supply at any time. 2. When used as mobile power supply, can add switch to SW pin, not in use when off, no static loss, very power-saving. 3. If not add switch to SW pin, it can also be shorted, and the output indicator can be welded down after all the tests are completed, which can reduce the current consumption without affecting the normal output of the circuit. 4. During the operation, various reasons (mistake touch, wrong connection, etc.) may trigger the module to enter the protection state and not output. After the problem is removed, the board charging port can be connected to the 5V charging, and the board can be activated and output again after power-on. 5. MOS components on the circuit board are easy to be damaged by static electricity, so please use a soldering iron with grounding wire and take anti-static measures.
