Description:
DS3231 Module is a Bread Board friendly extremely precise I2C real-time clock Module. This module was made using DS3231 RTC and AT24C32 EEPROM integrated with a temperature-compensated crystal oscillator. It also has a built-in comparator that monitors the status of VCC to detect power failures and automatically switch to the backup power supply.
The DS3231 is a RTC IC developed by Maxim Integrated. It is an extremely accurate and low-cost RTC IC with communication over I2C interface. An interesting feature of DS3231 RTC IC is that it has a built-in crystal oscillator and temperature sensor and hence you do not have to connect an external crystal.
Specifications:
- Model: DS3231 AT24C32
- Operating Voltage: 3.3 - 5 .5 V
- Clock Chip: High-Precision Clock Chip DS3231
- Clock Accuracy: 0-40 range, the accuracy 2ppm, the error was about 1 minute
Features:
- DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC), with an integrated temperature-compensated crystal oscillator (TCXO) and crystal.
- The device incorporates a battery input, disconnect the main power supply and maintains accurate timekeeping.
- it Provides two configurable alarm clock and a calendar can be set to a square wove output. Address and data are transferred serially through an I2C bidirectional bus.
- RTC maintains seconds, minutes, hours, day, date, month, and year information. Less than 31 days of the month, the end date will be automatically adjusted, including corrections for leap year.
Package included:
1 x DS3231 RTC Module Without Battery
