Pinout
4| Pin | Name | Functions | Notes |
|---|---|---|---|
| Vin | Power | POWER | Since the RTC can be powered from 2.3V to 5.5V power, you do not need a regulator or level shifter for 3.3V or 5V logic/power. |
| GND | Ground | GND | Common ground for power and logic |
| SCL | I2C Clock | I2C | Connect to your microcontroller's I2C clock line. This pin has a 10K pullup resistor to Vin. |
| SDA | I2C Data | I2C | Connect to your microcontroller's I2C data line. This pin has a 10K pullup resistor to Vin. |
