Describe:
  • Voltage: 3.3-5V, Memory chips: AT24C32 (storage capacity 32K)
  • Document link: http://tronixlabs.com/breakout-boards/real-time-clock/ds3231-real-time-clock-module/
  • About battery type: Battery is not included, you can use CR2032 or LIR2032 battery
  • Feature: The DS3231 is an RTC IC developed by Maxim Integrated. It is a low cost, extremely accurate RTC IC with communication over I2C Interface. An interesting feature of DS3231 RTC IC is that it has integrated crystal oscillator and temperature sensor and hence you don’t have to connect an external crystal.
