RTC DS1307 time module with AT24C32 EEPROM memory 32K
The DS1307 module is an accurate i2C Real Time Clock (RTC), with integrated temperature quartz oscillator and crystal. The date is automatically adjusted, including corrections for leap years. The module offers two configurable alarms and a calendar. Address and data are transferred bidirectionally via an IIC or I2C bus. The module has a very accurate digital temperature sensor integrated, which can be queried via an i2C interface. For the control of the DS1307 clock, you can find a suitable library in the Arduino Library Manager that you can install. For the control of the AT24C32 memory, you can find a suitable Arduino library at the following address: .cyberp/AT24Cx
