The High Accuracy Pi RTC is based on the clock chip DS3231, the DS3231 is a low-cost, extremely accurate I2C realtime clock (RTC). It can provide a real-time clock(RTC) for raspberry pi via the I2C interface. With the clock source from the TCXO(temperaturecompensated crystal oscillator), the RTC provides seconds, minutes, hours, day, date, month, and year information. The date at the end of the month is automatically adjusted for months with fewer than 31 days, including corrections for leap year.The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator.
The clock provides two programmable time-of-day alarms and a programmable square-wave output. The INT/SQW pin either generates an interrupt due to alarm condition or outputs a square-wave signal and the selection is controlled by the bit INTCN.
If you want to keep this module timing when the Raspberry Pi is powered off, you need to put a 3-Volt CR1225 lithium cell in the battery-holder.

I am building a Stratum 1 Time Server with my RBPi Zero WH, will this RTC module not interfere with Ublox NEO-M8N that needs Pins 1, 6, 8, 10, 13.Question by: electrogoodie on 2019-04-07 13:11:37
Sorry, I can't edit my question. It's Pin 12 and not 13. Thank you.Answer by: electrogoodie on 2019-04-07 09:15:30
This says it supports raspberry pi only, but would it be possible to connect the pins to an arduino and use the generic ds3231 libraries? Looking at your schematic, the only differences I notice is more resistors than arduino chips using the ds3231.Question by: George Gagaris on 2019-03-26 09:43:27
Hi George, It should work, we will test it tomorrow, and will feedback to you as soon as we get the result. Have a nice day.Answer by: admin on 2019-03-26 06:41:59
Hi George, We have tested it, it will work with Arduino, you can use this library: ### https://www.arduinolibraries.info/libraries/ds3231 ###. If you have any questions, please feel free to contact us. email@example.comAnswer by: admin on 2019-03-27 10:55:42
