Description
Module with real time clock DS1307 and backup battery. It allows you to read the time in hours, minutes, and seconds, date: month, day, year. The communication interface is I2C bus (SDA and SCL), data update frequency is 1 Hz (1 second).
The set consists of:
- Real Time Clock Module
- CR2032 battery
- Goldpin connector 1x5 - independent soldering
The product is compatible with Arduino The connect system makes it easy available inthe GitHub libraryfor users ofArduino. |
Connection
The supply voltage of5 Vis connected to the terminal marked with the same symbol. The I2C bus must be connected to the output ofSCL- clock line andSDAis the data line. PinSQWoutput is a square signal with the selected frequency (see page 3of the documentation).GNDis the ground system.
