UPS function board description:
When the power supply is powered, the load is directly supplied by the power supply via the boost circuit.
Once the power is turned off, the battery access is automatically activated to power the load via the boost circuit.
After the power is called, the power is restored from the power supply and the battery is also charged.
Charging ③ pin should be connected to DC 5V power, charging current 500mA maximum, the maximum power of the charging power supply used is at least 3w higher than the power consumption of the load, that is, the power supply can also charge enough battery current while loading . Example: If the load is 2w, you can use a 5V1A charging power supply; if 2w
