Special Features

  • 【Module introduction】DS3231 is an extremely accurate I2C real-time clock, with an integrated temperature-compensated crystal oscillator and crystal.The clock module has the characteristic of low power consumption, with 1 Hz and 32.768 kHz output
  • 【Can be used even if the power off】A precision temperature-compensated voltage reference and comparator circuit monitors the status of VCC to detect power failures, provide a reset output, and if necessary, automatically switch to the backup power supply.
  • 【Low Power Consumption and High precision】 Clock Module has the characteristic of low power consumption.The clock module is of ±3℃ digital temperature sensor, and the timing accuracy keep at ± 5ppm (± 0.432 sec / day).
  • 【Function】The clock module is of complete clock calendar functions include seconds, minutes, hours, day, date, month and year timing , provide valid until the year 2100 leap year compensation.
  • 【Convenient to use】The clock module itself can be adapted to 3.3 V and 5 V system, no level conversion, it is super convenient.
