Compared to the DS1302 solution, the DS3231 has many advantages, it function with a VCC ranging from 2.3V to 5.5V and has a battery backup. Unlike the DS1307, the DS3231 also has an integrated crystal (so no external crystal required), temperature sensor, 2 programmable time-of-day alarms, a 32.768 kHz output pin to ensure higher accuracy.Besides, there is also a EEPROM AT24C32 to supply you 32K EEPROM to store your data, it is the best choice for your application that needs recoding time, a built battery holder make this module suitable. It is a good substitution for the data logging shield, with even higher time precision.Features\nSize: 38mm (length) * 22mm (W) * 14mm (height)\nWeight: 8g\nOperating voltage :3.3 - 5 .5 V\nClock chip: high-precision clock chip DS3231\nClock Accuracy :0-40 ℃ range, the accuracy 2ppm, the error was about 1 minute\nCalendar alarm clock with two\nProgrammable square-wave output\nReal time clock generator seconds, minutes, hours, day, date, month and year timing and provide valid until the year 2100 leap year compensation\nChip temperature sensor comes with an accuracy of 3 ℃\nMemory chips: AT24C32 (storage capacity 32K)\nIIC bus interface, the maximum transmission speed of 400KHz (working voltage of 5V)\nCan be cascaded with other IIC device, 24C32 addresses can be shorted A0/A1/A2 modify default address is 0x57\nDownload & External Link24C32 DatasheetDS3231 DatasheetAT24C32 Arduino UsageDS3231 Arduino Usage","vendor":"Elecrow","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":3572,"title":"Default Title","sku":"EC-SMI3231DS","price":7.31,"compare_at_price":0.0,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
