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!...
A Feather board without ambition is a Feather board without FeatherWings! This is the DS3231 Precision RTC FeatherWing: it adds an extremely accurate I2C-integrated...
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...
This is a great battery-backed real time clock (RTC) that allows your Raspberry Pi project to keep track of time if the power is lost. Perfect for data-logging...
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 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.
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...
The real-time clock RTC breakout module employs the SD3031 chip with an integrated crystal oscillator and temperature compensator and a built-in 70-byte...
This shield includes an ultra low powered and super accurate RTC combined with a uSD Card reader and 2x STEMMA/QT connectors with separate IO, for two I2C channels, or 1x I2C and 1x UART.
