A look inside the DS3231 real-time clock

Thursday, August 10th, 2017

Pete posted an article taking a closer look at Maxim's DS3231 real-time clock: Fortunately, Maxim also offers the DS3231, which is advertised as an “Extremely Accurate I2C-Integrated RTC/TCXO/Crystal”. This chip has the 32kHz crystal integrated into the package itself and uses a built-in temperature sensor to periodically measure the temperature...

Using DS1307 and DS3231 real-time clock modules with Arduino

Friday, December 12th, 2014

John Boxall over at Tronixstuff has posted a detailed tutorial on how to on how to use DS1307 and DS3231 real-time clock modules with Arduino:  There are two main differences between the ICs on the real-time clock modules, which is the accuracy of the time-keeping. The DS1307 used in the first...
