## Description

A high-precision real-time clock (RTC) module based on the DS3231 IC, designed to plug directly into a Raspberry Pi B+ (and compatible with Arduino). The DS3231 maintains accurate timekeeping with ±5 ppm accuracy (±0.432 seconds per day) across −40 °C to +85 °C, and includes a coin cell battery backup to keep the clock running when the main board is powered off. The module supports both 3.3 V and 5 V systems without level conversion, making it compatible with a wide range of boards. Communication is via I²C at up to 400 kHz. Key Features DS3231 RTC IC – High-precision timekeeping with ±5 ppm accuracy Full Calendar – Seconds, minutes, hours, day, date, month, and year with leap year compensation valid until 2100 Battery Backup – Coin cell maintains time when main power is off Two Alarms – Programmable calendar alarms Temperature Sensor – On-chip digital temperature sensor (±3 °C accuracy) Clock Outputs – 1 Hz and 32.768 kHz square wave outputs 3.3 V / 5 V Compatible – No level shifting required Specifications RTC IC – DS3231 Accuracy – ±5 ppm (−40 °C to +85 °C) Interface – I²C (up to 400 kHz) Supply Voltage – 2.3–5.5 V Operating Temperature – −40 °C to +85 °C Ideal For Raspberry Pi projects requiring accurate timekeeping Data logging with timestamps Alarm clocks and scheduling systems Arduino projects needing a battery-backed RTC Resources DS3231 Datasheet (PDF) Arduino Demo Code (ZIP)
