RTC Real Time Clock DS3231, 32kB Memory, I2C, CR2032 battery, Arduino library

This RTC module with DS3231 compatible real time clock chip and additional 32kB EEPROM connects to micro controllers like Arduino or Raspberry Pi by a 2-wire I2C bus. We ship it with a fresh CR2032 backup battery to keep the correct time also when the power supply is disconnected.

Please find data sheets for DS3231 and 24C32N chips online.

• ​​​​​​​2-wire connection SDA/SCL
• Operating voltage 3.3V – 5.5V DC
• Box content: 1 x RTC module, 1 x CR2032 battery
• ​​​​​​​Libraries (for example Arduino) available

The CR2032 battery we ship with the module is NON rechargeable. If you want to use this battery for the module, the on-board charging circuit must be disconnected to avoid the risk of explosion! The charging circuit is designed for rechargeable lithium coin cells like ML2032, MIL2032, MR2032 etc.
