DIY Breakout RTC DS3231 "a.k.a Chronodot"

This is 2nd breakout board that i design and made full by my own hands, yeah ! :D. I like to etch and drill by my hand instead to order to make PCB to PCB services (of course only for the simple and relatively wide track of the PCB :D) The first breakout board that i made is for most famous RTC, DS1307. But i more prefer to use DS3231 because it's more accurate. I tested it with my DIY arduino clock, in one month the DS1307 is slower about 3 minutes (compare with my notebook system clock) while the DS3231 is just slower about 20 second because it's use internal crystal for timekeeping instead of external crystal like DS1307.

Extremely accurate RTC! :D

Hello world! lets arduino-ing

Hello world, this is my first posting in this blog, blog that i will use to share what i have done with arduino. Before this blog, i post my arduino experience in my Indonesian language blog, the "anything topic" blog. So i will move and post in English in this blog. Lets discuses about arduino world !
