Description

Module with real time clock and backup battery (battery included). 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(SDA and SCL), data update frequency is 1 Hz (1 second). It is the output of the temperature sensor DS18B20.

The product is compatible with Arduino

The connect system makes it easy available in the GitHub library for users of Arduino.

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 (see page 3 of the documentation).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 or the main module (for example,STM32Discovery or Arduino) via wires.
