## Description

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 Module  Charging voltage: DC 4.5V-5.5V (DC 5V recommended) Charging current : 0-2.1A Charging quiescent current : 100uA Full voltage: 4.2V+-1%. Discharge current: 0-2.4A; Discharge quiescent current : 50uA Discharge efficiency: up to 96% Output voltage: 5V Output current: 0-2.4A; Ambient temperature: -20&#xB0; to +85&#xB0; Size : 25 x 16 x 4mm Weight : 2.3g PCB board process: Shen Jin The 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 (Note: Output voltage >4.7/<5V at this time)  Package Included: 1 x module
