The DS3231 AT24C32 module is the perfect choice. It combines the DS3231 high-precision RTC (temperature compensated) with AT24C32 EEPROM (32Kb) on a single board, communicating via I2C. Less than 1 minute drift per year, leap year compensation until 2100. The module has a battery socket for backup (keeps time when main power is off). However, due to shipping restrictions, battery is NOT included – you need to supply your own LIR2032 (rechargeable) or CR2032. Ideal for data loggers, smart clocks, timed switches, or any system needing saved parameters.\u003c\/p\u003e\n\u003cp style=\"font-size:20px;font-weight:bold;text-align:left;color:rgb(67, 70, 73)\" class=\"word-break white-space mt-10\" align=\"left\"\u003e⚡ Quick Start Guide \u0026amp; Important Tips\u003c\/p\u003e\n\u003cdiv\u003e\u003cimg style=\"width:100%;height:auto\" width=\"100%\" height=\"auto\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sf1fe55d166e04cc1b847e13a5202b7a9i.jpg\" slate-data-type=\"image\"\u003e\u003c\/div\u003e\n\u003cp style=\"font-size:20px;font-weight:bold;text-align:left;color:rgb(67, 70, 73)\" class=\"word-break white-space mt-10\" align=\"left\"\u003e⚠️ Important Notes\u003c\/p\u003e\n\u003cp style=\"font-size:13px;font-weight:normal;text-align:left;color:rgb(67, 70, 73)\" class=\"word-break white-space mt-10\" align=\"left\"\u003e1. Battery: The module HAS a battery socket for backup (keeps time when power is off). However, battery is NOT included due to shipping restrictions.
