DS3231 RTC module with 32Kb EEPROM memory
RTC (Real Time Clock) module based on the DS3231 chip
SKU 3085-DS3231RTCEAN 8219671098090Item type: AssembledRTC (real-time clocks)
Description
| The RTC (Real Time Clock) module based on the DS3231 chip is the perfect choice for anyone looking for a highly accurate timekeeping device. With its 32Kb AT24C32 EEPROM memory, this module stores user data reliably. Thanks to the I2C interface, the temperature-compensated crystal oscillator (TCXO) and the output pin carrying a 32.768 kHz square-wave signal, this module can deliver extremely accurate timekeeping.
The RTC counts seconds, minutes, hours, day, date, month and year, with leap-year correction up to 2100, and can work in 12- or 24-hour mode, with AM (ante meridiem) and PM (post meridiem) indication. Thanks to the internal back-up system, the module also keeps data in memory when the power is off. This module is suitable for any application that needs an accurate time reference. A coin cell battery, to be bought separately, is recommended so that the module keeps running in the event of a power failure. |
