## Description

Notice:Trigger mode: low level trigger (ground)MCU users, if you accept a small load KEY can be connected to the microcontroller about 20S to give a low level allows the module to continue working!4-in-1 Charging / Discharging / Lithium Battery Protection / Battery Level Indicator ModuleCharging voltage: DC 4.5V-5.5V (DC 5V recommended)Charging current : 0-2.1ACharging quiescent current : 100uAFull voltage: 4.2V+-1%.Discharge current: 0-2.4A;Discharge quiescent current : 50uADischarge efficiency: up to 96%Output voltage: 5VOutput current: 0-2.4A;Ambient temperature: -20&#xB0; to +85&#xB0;Size : 25 x 16 x 4mmWeight : 2.3gPCB board process: Shen JinThe module comes with a lithium battery protection function (the lithium battery does not need to have a protection board, it does not matter if it has a protection board)Over-current protection (OCP)Overvoltage protection (OVP)Short Circuit Protection (SCP)Over-temperature protection (OTP)Pin description:1 VIN : Charge port positive input +2 GND : Charger Negative Input -3 BAT : Lithium Battery +4 GND : Lithium Battery -5 GND : Output negative output -6 VOUT: Output Positive Output +7 KEY : Output Enable Trigger Port (Low Pulse Trigger)1 In the discharging mode (the charging mode KEY function is invalid), the KEY port is triggered once and the output is turned on; the KEY port is triggered twice in succession and the output is turned off.2 The first time you access the load, the output is automatically turned on. If the load is less than 50MA, the output will be turned off after 30 seconds; if the load is greater than 50MA, the output will be continuously turned on.3 Allow discharge while charging (<
