| Pin | Description |
|---|---|
| VDD | Supply voltage in the range from 2.7 V to 5.5 V. |
| GND | The ground of the system. |
| SCL | Clock line of the I2C bus (installed resistor pulling-up 10 kΩ). |
| SDA | The data line of the I2C bus (installed resistorpulling-up 10 kΩ). |
| ALERT | The external interrupt of open collector type. |
| A0, A1, A2 | Pins of address selection of I2C bus. Default adress is: 0x18. Indicating the high status on a single bit will lead to the change of address in accordance with patterns: 0x18 + A2 + A1 + A0. For example, when indicating a high statusn on all bits, the address will be: 0x18 + 4 + 2 + 1. When we indicate a high status only on A2 and A0, then: 0x18 + 4 + 1 = 0x1D. |
