It keeps accurate time and date for Arduino, ESP32, STM32 and Raspberry Pi projects. An onboard rechargeable backup cell keeps the clock running when main power is off.\u003c\/p\u003e\n\u003cp\u003eIt works on both 3.3V and 5V, and its 5-pin female header plugs straight onto the Raspberry Pi GPIO header, so no wiring or level shifter is needed.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDS3231 RTC with built-in temperature-compensated crystal (about ±2 ppm from 0–40°C)\u003c\/li\u003e\n\u003cli\u003eTracks seconds, minutes, hours, day, date, month and year, with leap-year correction up to 2100\u003c\/li\u003e\n\u003cli\u003eTwo programmable time-of-day alarms\u003c\/li\u003e\n\u003cli\u003eSquare-wave output (1 Hz) and 32.768 kHz output\u003c\/li\u003e\n\u003cli\u003eOnboard digital temperature sensor\u003c\/li\u003e\n\u003cli\u003eSoldered rechargeable coin cell, recharged from the board supply, keeps time during power loss\u003c\/li\u003e\n\u003cli\u003e5-pin female header (+, D, C, NC, −) that sits directly on Raspberry Pi pins 1–9\u003c\/li\u003e\n\u003cli\u003eFast-mode I2C interface (400 kHz)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eChip: DS3231\u003c\/li\u003e\n\u003cli\u003eSupply voltage: 2.3V – 5.5V (3.3V and 5V compatible)\u003c\/li\u003e\n\u003cli\u003eInterface: I2C (address 0x68)\u003c\/li\u003e\n\u003cli\u003eConnector: 5-pin female header\u003c\/li\u003e\n\u003cli\u003eOperating temperature: -40°C to +85°C\u003c\/li\u003e\n\u003cli\u003eBackup: rechargeable coin cell (soldered, included)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eData loggers and timestamped sensor readings\u003c\/li\u003e\n\u003cli\u003eDigital clocks, timers and alarms\u003c\/li\u003e\n\u003cli\u003eScheduled automation and home-automation controllers\u003c\/li\u003e\n\u003cli\u003eAdding a hardware clock to a Raspberry Pi with no network\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePackage includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 × DS3231 RTC Module with battery\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Anu Electronics","offers":[{"title":"Default Title","offer_id":48071191363761,"sku":"ANU-RTC-DS3231-MOD","price":269.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0634\/3606\/2897\/files\/ds3231-rtc-module-1_ec3e0d1b-d5bd-4fc6-aa55-5d7ff6a1a8dc.jpg?v=1792510169","url":"https:\/\/anuelectronics.com\/products\/ds3231-rtc-real-time-clock-module-3-3v-5v-with-battery","provider":"Anu Electronics","version":"1.0","type":"link"}
