Pinout
6| Pin | Name | Functions | Notes |
|---|---|---|---|
| VIN | Power Input | POWER | The chip can safely run from 3-5VDC. To power the board, give it the same power as the logic level of your microcontroller - e.g., for a 5V microcontroller like Arduino, use 5V. |
| GND | Ground | GND | Common ground for power and logic |
| SCL | I2C Clock | I2C | Connect to your microcontroller's I2C clock line. There's a 10K pullup on this pin. |
| SDA | I2C Data | I2C | Connect to your microcontroller's I2C data line. There's a 10K pullup on this pin. |
| INT | Interrupt | GPIO | Interrupt signal out, you can set this up to pull low when the voltage or percentage drops below a threshold. Pulled up to VIN with a 10K resistor. |
| Therm | Temperature Sensor Input | GPIO | Connect a 10K thermistor to the THERM pin to read the battery pack temperature. The other side of the thermistor goes to ground. |
