Description
Tiny RTC I2C 24C32 Memory DS1307 Clock Module
Module with real time clock and backup battery.
It allows you to read the time in hours, minutes, and seconds, date: month, day, year. It has 32 KB of EEPROM.
The communication interface is an I2C bus. It is the output of the temperature sensor DS18B20.
Connection
The supply voltage of5 Vis connected to the terminal marked with the same symbol. The I2C bus must be connected to the outputs SCL– clock line andSDA – data line. PinSQis the output of a rectangular signal with the selected frequency .GNDis the ground system.
| PIN | DESCRIPTION |
|---|---|
| SQ | The output of the square wave signal. |
| DS | The output of the temperature sensor DS18B20. |
| SCL | Clock line of I2C interface. |
| SDA | Data line of I2C interface. |
| VCC | The supply voltage of 5 V. |
| GND | The ground of the system. |
| BAT | The battery output. |
Connectors
Outputs are solder fields for soldering goldpin connectors- 2.54 mm raster (not included). Thanks to them, it is possible to connect the system with the breakout board the main module (for example,STM32Discovery or Arduino) via wires.
