RTC DS 3231 Module

RTC DS 3231 Module

Module parameters:

  • Size: 38mm (length) * 22mm (W) * 14mm (height)
  • Operating voltage :3.3 – 5 .5 V
  • clock chip: high-precision clock chip DS3231
  • Clock Accuracy :0-40 ℃ range, the accuracy 2ppm,  the error was about 1 minute
  • Calendar alarm clock with two
  • Programmable square-wave output
  • Real time clock generator seconds, minutes, hours,  day, date, month and year timing and provide valid until the year 2100 leap year  compensation
  • Chip temperature sensor comes with an accuracy of  ± 3 ℃
  • Memory chips: AT24C32 (storage capacity 32K)
  • IIC bus interface, the maximum transmission speed  of 400KHz (working voltage of 5V)
  • Can be cascaded with other IIC device, 24C32  addresses can be shorted A0/A1/A2 modify default address is 0x57
  • With rechargeable battery LIR2032, to ensure the  system after power failure, the clock move any natural normal
  • Wiring instructions (with Arduino uno r3 for  example):
    SCL → A5
    SDA → A4
    VCC → 5V
    GND → GND
