• DS1307 chipset
• optional: CR1220 backup battery
Pinout
• 5 V: 5 V power supply
• D1: SCL
• D2: SDA
• GND: Ground

The DS1302 chip uses a simple serial interface and sample code is available for Arduino, Raspberry Pi and many others.
The real time clock counts seconds, minutes, hours, the date of the month, the month, the day of the week and the year with leap year compensation valid until 2100.
• serial inputs and outputs for minimum pin count
• 2 V to 5.5 V full operation
• requires less than 300 nA at 2 V
• single byte or multi-byte data transfer for reading or writing clock or RAM data
Note
• battery not included (battery see accessories)

Technical data
• for all current Raspberry Pi versions
• high accuracy
• energy efficient
• 2 calendar clocks
• 1 Hz and 32.768 kHz output
• I2C bus (400 kHz)
• voltage: 2.3 ... 5.5 V DC
• digital temperature sensor
• dimensions: 15 x 13 x 14 mm

The main advantage of RTCs is that they have battery backup, which keeps the clock/calendar running even in the event of a power failure. An exceptionally small amount of power is required to keep the RTC running.
Technical features
- DS1307 RTC
- I²C interface
- for LIR2032 (not included)
- less than 500 nA in backup mode
