DS3231 RTC (Real Time Clock) Module

Description

DS3231 RTC Breakout – Real Time Clock (RTC) Breakout Module The DS3231 RTC Breakout features the DS3231, an extremely accurate I2C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The DS3231 maintains precise timekeeping, with an accuracy of ±2ppm from 0°C to +40°C and ±3.5ppm from -40°C to +85°C, making it ideal for applications where reliable timekeeping is essential. The module includes a battery backup input to ensure continuous operation even during power interruptions. With its I2C interface, the DS3231 easily integrates with microcontrollers. Additional features include two programmable alarms, a square-wave output, a reset function, and a built-in temperature sensor. Features : Real-time clock tracks seconds, minutes, hours, day, date, month, and year Leap-year compensation valid up to 2100 Accuracy: ±2ppm (0°C to +40°C), ±3.5ppm (-40°C to +85°C) Battery backup for uninterrupted timekeeping I2C interface Two programmable time-of-day alarms Programmable square-wave output Low power consumption Operating voltage: 2.3V to 5.5V Specifications : Operating Voltage 2.3 to 5.5V (3.3 or 5V typical) Current Consumption < 300µA (typ.) Accuracy (0-40°C) ± 2ppm Battery CR2032 (3V Coin) DS3231 RTC Breakout Pinout : Datasheet : DS3231
