- 15:39, 1 August 2024 JMerkle talk contribs created page DS3231 RTC (Created page with "The DS3231 RTC is a low cost, battery backup, Real Time Clock, that connects to an I2C bus, providing accurate time information. Many DS3231 modules, like this one, https://www.ebay.com/itm/314250880191, have two I2C devices on-board, a DS3231 RTC and a AT24C32 EEPROM, allowing the storage of information into non-volatile memory.")
