DS3231 RTC Module
The DS3231 RTC Module is a compact Real-Time Clock module designed for Raspberry Pi that can also be utilized with Arduino. It runs on both 3.3V and 5V and has a built-in self-adjustment feature. Additionally, it offers battery backup for uninterrupted timing and boasts low power consumption. With its comprehensive clock functions ranging from seconds to years, it ensures accurate timing up to the year 2100.
This DS3231 RTC module includes two calendar alarms, a 1Hz output, and a 32.768kHz output. The reset output and input buttons are debounced for use with a high-speed (400KHz) I2C serial bus. While some RTC modules are designed for 5V operation, the Raspberry Pi runs on 3.3V. Thankfully, this convenient module is compatible with 3.3V and allows you to add an RTC to your Raspberry Pi seamlessly.
