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 |
here my design of the DS3231 breakout, use SMD 1206 for pull-up resistor , it's just cost me about Rp. 12.000 (about 1 USD ) that i use to make the PCB because i got the 1-tube free-IC from free-sample program from Maxim Integrated, many thanks Maxim Integrated!.
