DS3231 AT24C32 Real Time Clock Module I2C RTC for Arduino

(With Out Battery Inside)


• Dimension: 38mm* 22mm * 14mm

• Weight: 8g

• Working voltage: 3.3 - 5.5V

• Clock chip: high-precision clock chip DS3231

• Clock accuracy within range: 0-40°, accuracy 2ppm, about 1 minute in error

• Programmable square-wave output

• Real-time clock, it can generate seconds, minutes, hours, day, date, month and year, and provide time until 2100, and with leap year compensation.

• Internal chip temperature sensor comes with an accuracy of ± 3°

• Memory chips: AT24C32 (storage capacity of 32K)

• I2C bus interface, the maximum transmission speed of 400KHz (working voltage of 5V)

• I2C other devices can be cascaded, 24C32 address can be modified by a short circuit A0/A1/A2, the default address is 0x57

• Come with a battery CR2032, the clock is still working even power off.
