Note: In the discharge mode (the charging mode KEY function is invalid), the KEY port is triggered once, and the output is turned on; the KEY port is continuously triggered twice, and the output is turned off.
When the load is first connected, the output will be automatically turned on. If the small fish 50MA is loaded, the output will be turned off after 30 seconds; if the load is greater than 50MA, the output will be continuously turned on. Allow one side to discharge while charging (Note: this is the output voltage Greater than 4.7/ less than 5V)
Wiring Instructions: When the module is plugged in, the output will switch to external power supply (it will be powered off for 0.3s). When charging, the output voltage will be less than Greater than 4.7/ less than 5V, depending on the charger load capacity!
Trigger mode: low level trigger (ground); Connect to the single-chip microcomputer, if the connection is less than the load KEY, you can connect the single-chip microcomputer for about 20s to give a low level to keep the module working continuously.
