Ships Same Day if Ordered Before Noon Pacific Time

The DS3231 is a high precision real time clock (RTC) module that is ideal for a variety of applications. This module also includes an AT24C32 EEPROM, which provides 4096 bytes of non-volatile memory. This memory can be used to store data such as configuration settings, calibration data, or user data.

The DS3231 features an integrated temperature-compensated crystal oscillator (TCXO), which ensures that it keeps accurate time even in changing temperature conditions. The module also has a built-in alarm function, which can be used to wake up a microcontroller or other device at a specific time.

The DS3231 is easy to use and can be interfaced with a variety of microcontrollers and other devices using the I2C protocol. The module is also breadboard compatible, making it easy to use with a variety of prototyping and development boards.
