Arduino Tiny RTC I2C Real Time Clock Pinout |
||
| PIN | Description | Comment |
| BAT | Battery voltage | To monitor the battery voltage, or not connected |
| GND | Ground | Ground |
| VCC | 5V supply | Power the module and charge |
| SDA | I2C data | I2C data for the RTC |
| SCL | I2C clock | I2C clock for the RTC |
| DS | DS18B20 Temp. Sensor output | One wire interface |
| SQ | Square wave output | Normally not used |
The I2C wires "SDA" and "SCL" are the data line and clock line, they should be connected to the corresponding pins depending on the Arduino board.
| Board | I2C / TWI pins |
| Uno, Ethernet | A4 (SDA), A5 (SCL) |
| Mega2560 | 20 (SDA), 21 (SCL) |
| Leonardo | 2 (SDA), 3 (SCL) |
| Due | 20 (SDA), 21 (SCL), SDA1, SCL1 |
