상품특징
Make sure this fits by entering your model number.High Precision: The DS3231 is a low-cost, extremely accurate I2C realtime clock (RTC) with an integrated temperature compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input, and maintains accurate timekeeping when main power to the device is interrupted. The integration of the crystal resonator enhances the long-term accuracy of the device as well as reduces the piece-part count in a manufacturing line.High Suitability: The module can work on either 3.3 or 5 V which makes it suitable for many development platforms or microcontrollers.High Reliability: The battery can maintain the information for more than a year.A precision temperature-compensated voltage reference and comparator circuit monitors the status of VCC to detect power failures, to provide a reset output, and to automatically switch to the backup supply when necessary. Additionally, the RST pin is monitored as a pushbutton input for generating a reset externally.Auto Tuning: The DS3231 is available in commercial and industrial temperature ranges, and is offered in a 16-pin, 300-mil SO package. The RTC maintains seconds, minutes, hours, day, date, month, and year information.The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator.Built-in Multiple Functions: Two programmable time-of day alarms and a programmable square-wave output are provided. Address and data are transferred serially through an I2C bidirectional bus.

The DS3231 is a low-cost, highly accurate Real Time Clock which can maintain hours, minutes and seconds, as well as, day, month and year information. Also, it has automatic compensation for leap-years and for months with fewer than 31 days.This accessory plugs on top of your Pi's GPIO pins and contains a clock chip and a super-cap that allows your Raspberry Pi to remember the time! Technical Specifications: Accuracy ±2ppm from 0°C to +40°C Accuracy ±3.5ppm from -40°C to +85°C Battery Backup Input for Continuous Timekeeping Low-Power Consumption Real-Time Clock Counts Seconds, Minutes,Hours, Day, Date, Month, and Year with Leap Year Compensation Valid Up to 2100 Two Time-of-Day Alarms Programmable Square-Wave Output Fast (400kHz) I2C Interface Digital Temp Sensor Output: ±3°C Accuracy Register for Aging Trim RST Input/Output UL Recognized Operating Temperature Ranges: Commercial (0°C to +70°C) and Industrial (-40°C to +85°C) Operating voltage :3.3 - 5 .5 V Clock chip: High-precision clock chip DS3231 Size: 14mm×14mm×10mm / 0.55″ ×0.55″×0.39″(L×W×H) Package includes: 2 x DS3231 AT24C32 IIC High Precision Real Time Clock Module
