Description

DS1307 RTC time module for Arduino – real time clock

RTC module with DS1307 real-time clock.

RTC Module Features:

• DS1307 real-time clock module with battery backup.
• Allows you to read the time in the form of hour, minute and second and the date: month day, year.
• The communication interface is the I2C bus (SDA and SCL lines)
• The data refresh rate is 1 Hz (1 second).
• Available data:
  • Time: hour (AM, PM), minute, second
  • Date: month, day, year
• Accurate calendar to the year 2100
• The module has goldpin leads, allowing it to be connected to any runner kit or dedicated circuit board using available wires.
• Compatible with uNO arduino i MEGA 2560
• lED signaling
• Application for contact boards, runtime modules, arduino, etc.
