RTC& EEPROM Module DS3231 AT24C32
€6.60
Tax included
The DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO). Compared to the DS1302, it operates from 2.3V to 5.5V and includes a battery backup. Unlike the DS1307, it features an integrated crystal, temperature sensor, 2 programmable alarms, and a 32.768 kHz output. The module also includes an AT24C32 EEPROM (32K) for data storage and a built-in battery holder, offering superior precision compared to standard data logging shields.
The DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. Compared to the DS1302 solution, the DS3231 offers many advantages: it operates with a VCC ranging from 2.3V to 5.5V and includes a battery backup. Unlike the DS1307, the DS3231 features an integrated crystal (no external crystal required), a temperature sensor, 2 programmable time-of-day alarms, and a 32.768 kHz output pin to ensure higher accuracy.
Besides, the module includes an AT24C32 EEPROM providing 32K of storage for your data. It is the ideal choice for applications requiring time logging. A built-in battery holder makes this module suitable for long-term use. It is a superior alternative to the data logging shield, offering even higher time precision.
