With the RTC DS3231, the date and time can be saved even if the corresponding circuit is de-energized. Communication takes place via the simple I2C bus.
- RTC DS3231 AT24C32 Memory Real Time Clock I2C Module for Arduino AVR UNO ARM PIC
- The DS3231 module is an accurate I2C real-time clock (RTC), with an integrated temperature - crystal oscillator (TCXO) and crystal.
- CR2032 button cell battery.
- Possible queries: seconds, minutes, hours, day, date, month and year.
- Date is automatically adjusted, including corrections for leap years.
- The clock operates in either the 24-hour AM/PM mode or 12-hour format. The module offers two configurable "alarm clocks" and a calendar.
- Address and data are serially transmitted bidirectionally via an I2C bus.
- The IC has an integrated, very precise digital temperature sensor that can be queried via the I2C interface.
Specifications:
- Operating voltage: 3.3 to 5.5V
- RTC chip: DS3231SN
- Clock accuracy: 2ppm @0-40 degrees
- Calendar with 2 "alarm clocks"
- Programmable square wave signal output
- Eeprom: AT24C32 ( storage capacity 32K)
- I2C bus interface, maximum transmission speed of 400 kHz (at VCC 5V)
- can be cascaded with other I2C modules
- CR2032 battery, in the event of a power failure, the RTC Stand-Alone continues to run
- Dimension: approx. 38 x 22 x 15mm (length with pin strip approx. 44mm)
- Weight approx. 8g
Scope of delivery:
Before programming with the Arduino IDE, please run the test program in "Documents"
- 1x DS3231 RTC module
