Which better, DS3234 or DS3231

Postby shahrul » Wed Apr 24, 2013 10:42 am

I have this two module RTC DS3234 and RTC DS3231. DS3234 I bought at ebay long time ago (over 1 year) and DS3231 I bought at Cytron a few month ago. First one use SPI and second one use I2C. Just want to know which one more accurate.
But for learning process, ofcourse I will interface both module because I love the knowledge.
