Description:

The DS3231 AT24C32 IIC Hi Precision RTC Real Time Clock Memory Module is a highly accurate I2C real-time clock (RTC) that is designed for use with Arduino boards. It features an integrated temperature-compensated crystal oscillator (TCXO) and crystal, and can be used to maintain accurate timekeeping even when disconnected from the main power supply.

Some key features of this module include:

• Size: 38mm (length) * 22mm (W) * 14mm (height)
• Weight: 8g
• Operating voltage: 3.3-5.5V
• Clock chip: High-precision clock chip DS3231
• Clock accuracy: 0-40C 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
• Chip temperature sensor with an accuracy of ± 3C
• Memory chip: AT24C32 (storage capacity 32K)
• IIC bus interface, the maximum transmission speed of 400KHz (working voltage of 5V)
• Can be cascaded with other IIC devices
• With rechargeable battery LIR2032, to ensure the system after power failure, the clock move any natural normal
• Packing: single anti-static packaging
• The module comes with a rechargeable battery LIR2032, to ensure the system after power failure, the clock move any natural normal. It also
• comes with wiring instructions for connecting it to an Arduino Uno R3 board.
