The datasheet for the DS3231 explains that this part is an "Extremely Accurate I²C-Integrated RTC/TCXO/Crystal". And, hey, it does exactly what it says on the tin! This Real Time Clock (RTC) is the most precise you can get in a small, low-power package.

The DS1307 Real Time Clock developed by one of our designers: Waiman. The module comes fully assembled and pre-programmed with the current time (ok, so it's our current time - MST).

This is a great battery-backed real time clock (RTC) that allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. Perfect for data-logging, clock-building, time stamping, timers, and alarms, etc. Equipped with PCF8523 RTC - it can run from 3.3V or 5V power & logic!

We're glad to introduce a new member in Gravity family: Gravity I2C SD2405 RTC module. This is an extremely accurate I2C real-time clock (RTC) with crystal compensation...

The Pico-RTC-DS3231 is a RTC expansion module specialized for Raspberry Pi Pico. It incorporates high precision RTC chip DS3231 and uses I2C bus for communication. More external sensors are allowed to be connected thanks to the stackable design.

his module adds a real, hardware clock to your Raspberry Pi. This means that having an accurate system clock is no longer dependent on having an internet connection - perfect for Pis that are remote or have only intermittent access to the internet, but still need to log data or schedule tasks.

This precise RTC adopts DS3231M chip, which integrates MEMS resonator and temperature compensator. Compared to quartz crystal clock, the real-time clock reduces...

The Raspberry Pi is a great low cost computer with thousands of different uses but one thing it does not come with is a real-time clock. This means that every time you switch off your Raspberry Pi it forgets what the time is and you have to manually set it again next time you switch your Raspberry Pi on.

This real-time clock module (RTC) uses the DS3232 chip that integrates a crystal resonator and a temperature compensator, which improves the long-term accuracy of...

This RTC module is specifically designed for the Raspberry Pi. It communicates with Raspberry Pi through I2C bus and includes a Maxim DS1307 on the board to keep a real time clock for a long time after the Pi has powered down. Just set a serial port, and you have a convenient way of online debugging using TTL. Supports Raspberry Pi B/A+/B+/2 model B/3 model B.
