DS3231 AT24C32 Real Time Clock Module I2C RTC for Arduino

Description:

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.
