Pinout Definition
| IN | Power input (5V 3A) |
|---|---|
| OUT | UPS output (5V 2.5A) |
| GND | ground |
| UPS OFF | turn off UPS power output when connected to PWR pin |
| BOOT | Batteries activation (pull low for 500ms and then pull high) |
| CHARGE | Charge indication (low level indicates charging) |
| SCL | I2C clock |
| SDA | I2C data |
| PWR | UPS ON/OFF (turn off UPS power output when connected to UPS OFF pin) |
Note: When using pin headers for charging and discharging, it is recommended to connect all input and output pins for 2.5A output current to reduce pin stress
